pencils cost .50 notebooks cost .30 henry spent $1.40 how many of each did he buy if he bought the same number

Question

of pencils and notebooks?

Answer 1

Hmmm... you won't have a whole number of notebooks or pencils...
0.50n + 0.30n = 1.40
0.80n = 1.40
n = 140/80
n = 7/4
n = 1 3/4 notebooks and 1 3/4 pencils.

You probably meant $2.40 in which case the answer would be 3 of each.

Answer 2

Say that Dan bought 3 pencils and each pencil cost 5 cents You know logically that it took 15 cents for him to buy those pencils. He would need one nickle for each pencil he bought, or 3 nickles. A nickle = 5 cents. 3 * 5 = 15 In this case, you use the same logic but you don't know how many he bought or what they cost. What you know is he bought some number of pencils and each pencil cost some amount of money. You still multiply the number of pencils by the price per pencil. So you would express it as x * y = xy.

Answer 3

1 pencil because if he bought 3 it would be too much and if he bought 2 there would be .40 and that is nothing up there so it has to be 1. 3 notebooks because there is .90 cents left over and .90/3=3.
1 pencil
3 notebooks

Answer 4

If Henry bought the same of each he could buy three pencils for .50 each which equals 1.50. If he bought three notebooks at .30 each that would equal .90. 1.50 plus .90 equals 2.40, maybe that is what the total should be, not 1.40

Answer 5

since he's buying the same number of each, you can call this number (n).

.50n + .30n = 1.40 (since the number of pencils @ .50 added to the number of notebooks for .30 equals a total of 1.40).

so, .80n = 1.40

n = 1.75 of each (which doesn't really make sense how you could buy 1.75 notebooks and 1.75 pencils but....) maybe someone else will get a different number =)

Answer 6

1 notebook
1 pencil
and the rest on pens

Answer 7

bought 2 pencils and 2 notebooks and had a coupon for 12.5% off =)

2 pencils and 2 notebooks = $1.60 - 12.5% = $1.40

have a great day

Answer 8

3 note books, 1 pencil

Answer 9

1 and 3/4's?

Answer 10

You must have copied the question wrong. the only way to work this is if he bought fractions of notebooks and pencils..something is wrong with what you wrote...
