Answer:

238 gallons 7%
119 gallons 1%

Step-by-step explanation:

Let h represent the number of gallons of high butterfat content milk. Then 357-h will be the number of gallons of 1% milk. The total amount of butterfat in the mix is ...

0.07h +0.01(357 -h) = 0.05(357)

0.06h = 14.28 . . . . . . . . . . subtract 3.57, collect terms

h = 238 . . . . . . . . . . divide by 0.06

357-h = 357 -238 = 119

238 gallons of 7% and 119 gallons of 1% are needed.
