Question

Carrie is buying bulk candy for a high school fundraiser. She buys 1000 candy bars for $350. What is the unit cost per candy bar?

a. $.30
b. $.35
c. $.45
d. $1.35

Answer 1

.35 per candy bar is what she paid for them

Answer 2

we can make a proportion:
let x = cost per 1 candy bar

`(x)/(350) = (1)/(1000)`
x is already explained
350 is $350
1 is 1 candy bar
1000 is 1000 candy bars
then, we cross multiply to get:
350=1000x
divide both sides by 1000 to get
x = 0.35
so each candy bar costs $0.35, or 35¢ (the unit cost per candy bar is $0.35, or 35¢)
