1000 candy bars ... $350
1 candy bar ... $x = ?
If you would like to know what is the unit cost per candy bar, you can calculate this using the following steps:
1000 * x = 350 * 1
1000 * x = 350 /1000
x = 350 / 1000
x = $0.35
Result: She can buy 1 candy bar for $0.35, so the correct result would be B) $.35.
You would do 157.5/35 to find how much gas she needs
157/35=4.5
She'll need 4.5gallons of gas
The answer is A. Good luck man!! :)
