How many 1-gallon bottles of juice will Frank need to purchase?. . (1 quart = 32 fluid ounces, 1 gallon = 4 quarts). . 1 bottle. . 2 bottles. . 3 bottles. . 4 bottles

Answer 1

35 juice-cups * 12 fl oz / juice-cup * 1 qt/32 fl oz * a gallon/ 4 qt = 3.28125 gallons

Then he needs to buy 4 1-gallon bottles.

Answer 2

step
`1`

Find the total volume of juice required

Multiply
`35` juice-cups by
`12` fluid ounces

so

`35*12=420\ fluid\ onces`

step
`2`

Find the 1-gallon bottles of juice required for
`420` ounces

we know that

`0.25\ gal = 32\ fluid\ ounces`

by proportion

`(0.25)/(32)(gal)/(ounces)=(x)/(420) (gal)/(ounces)`

`x=(420*0.25)/(32)\\\\x=3.28\ gal`

we know that

The juice comes in 1-gallon bottles

so

`3.28\ gal` ------>
`3.28\ bottles`

round up------->
`4\ bottles`

therefore

the answer is

`4\ bottles`
