If a ketchup packet costs 1.3 cents, How many ketchup packets can I buy for $1,000?

Answer 1

76,923 packets. You better like french fries...

Answer 2

There is a very easy way to solve problems like this. It is called "unit conversion" and if you are going to take any science classes you should memorize how to do this.

You have $1000 and you know there are 100 cents in $1

So we say "there is 100 cents per dollar" and mathematically it looks like this: 100 cents/1 dollar

We can also say "there's a dollar per 100 cents" so we can flip it mathematically like this: 1 dollar/100 cents

Looking at the ketchup we can say "it's 1.3 cents per pack" which is 1.3 cents/1 pack or we can flip it.

This is what you do...

(1000 dollars)*(100 cents/1 dollar)*(1 packet/1.3 cents) = #

where # is the number of packets $1000 will buy.

The way you figure out how to set this up is, taking what you have, you want to multply it by the unit conversion such that what you have cancels so it's on the bottom, and what you want is on the top.

I started with 1000 dollars and I wanted the dollars to cancel and I wanted to end up with cents for my next conversion. This is like having 5*(3/5) the 5 cancels and I'm left with 3.

Answer 3

first you convert dollars to cents
if 1 dollar is a 100 cents then 1000 dollars are 100000 cents

then use cross multiplication:

1 ketchup packet 1.3 cents
? 100000cents

(100000 * 1) / 1.3
= 76923 packets

Answer 4

$1000 x 100 cents = 100000 cents / 1.3 ketchup packets = 76923 ketchup packets

Answer 5

$1000 is also 100000 cents.
so the answer is 100000 divide by 1.3 = 76, 923 ketchup packets

Answer 6

there are a hundred cents in a dollar right?
so...
(1000x100)/1.3= 76,923.08
more realistically: 76,923 ketchup packets

Answer 7

As there crammed the device warmth seals the packets, that day the line of plastic they use exchange into off centre slightly, they regularly are discarded with the aid of high quality controls, they are something to hold on too for a snort, no actual value.

Answer 8

The answer is76925.Take
(1000*100)/1.3

Answer 9

1.3 cents a ketchup packet? man that's cheap, i want some to...

Answer 10

You can only buy 76,000 packets. You can't buy the other 923 because they are sold in boxes of 1,000 packets.

Answer 11

1000 * 100 / 1.3 = 76923.07...
Therefore you can buy 76,923 packets.
