Are you good with math!? I need help!?

Question

Ok if i know that from sebring to pittsburgh is 78.76 miles and it took 1/4 tank of gas. Then to get from sebring to new york its 421.71 miles. How much will i have to pay for gas to go to new york assuming that i have to fill the tank from E before we start and gas is running about $2.15

Sorry if this is really comfusing im not oo good with math or how to explain it!

umm 12 gallon i think. i know i get 28 city miles and 34 highway

Answer 1

78.76 miles/.25 tank = 421.71 miles/x
Multiply by 0.25 x tank/mile (cancel out as many units as you can):
78.76 x = 105.4275 tank
Divide by 78.76:
x≈1.339 tanks of gas
The amount you have to pay for gas to get from sebring to new york is then 1.339*$2.15*(the number of gallons in your tank). You will need to stop at at least 1 gas station along the way.

Answer 2

Try a proportion - always helps me. But it's confusing to mix fractions with decimals, so change the 1/4 tank to .25.

Then 78.76 mi/ .25 tank = 421.71mi/ x

Now cross multiply: 78.76 x = (.25)(421.71)
So x would be the product of .25 times 421.71 divided by 78.76.

This would give you the number of tanks to go to New York. Now you need to know how many gallons the tank holds, then multiply by $2.15 to find total cost.

i'm maths instructor sending you this tips: a million) do no longer restore particular time, 2) pastime is the motivating component to study mathematics. 3) very maximum important aspect to be said is "practice Examples and workouts only. 4) do no longer bypass over any financial disaster. 5) if you're a student of state board,do no longer study something from out area the textual content e book. 6) Refer previous 3 hundred and sixty 5 days questions. 6) if ISC, you should refer extra books. 7) pastime and exertions with positive would convey you 100percentsuccesses

Answer 4

You set up a proportion.

1/4 tanks of gas/78.76mi.=x/421.71

Then you cross multiply.

Then you divide by 78.76 and get a total of 1.3385919248349413. Then you estimate that to 1.4 tanks of gas.

Then you multiply 1.4 by 2.15. Getting a total of $3.01.

Answer 5

It is just a ratio:
78.76 x 421.71
_____ _____
.25 X

cross multiply and solve for X,
X = 1.339 tanks of gas, multiply by the cost and the final answer (cost) is $2.88

note the X is suppose to be under the 421.71

Answer 6

You're missing information. In order to calculate how much it would be at $2.15/gallon you need to know how many gallons your gas tank holds.

Answer 7

How many gallons do you fill your tank with each time? Multiply that number by 2.88, and you'll have the cost of your trip's gas.

Answer 8

Inconclusive. How many gallons of gas does the tank hold?

Answer 9

your fuel consumption is (78.76 mi)/((1/4) tank), or 315.04 mi/tank. To get to New York is going to take 421.71 mi / 315.04mi/tank, or 1.3386 tanks. You will need to refuel twice. I'm sure you meant $2.15/gal, and not $2.15/tank, so to finish, we need to know the capacity of your tank, preferably in gallons.

A 12 gal. tank would give you 26.25 mpg.
Using this number,
(421.71 mi/26.25 mpg)*$2.15/gal. = $34.54

28 mpg city yields $32.38, and 34 mpg hwy yields $26.67.

Answer 10

0.25:78.76::x:421.71
x=421.71*0.25/78.76
=1.34
so total gas requirement=1.34+0.25=1.59 tanks
now if you tell me the capacity of the tank in gallons and confirm gas is running at $2.15/gallon i can calculate the amount you have to pay for gas
