17. a restaurant has one type of milk that has 2% fat and another that has 7% fat. How many quarts of each type does the restaurant need to make 40 quarts of a milk mixture that 5% fat (1 point)
A. 10 lawns
B. 50 lawns
C. 100 lawns
D. 1,000 lawns
If there are x quarts of 2% fat, then the rest (40-x) is 7%. So, just add up the fat content:
.02x + .07(40-x) = .05(40)
x = 16
Looks like (B) to me.
You can actually get the right answer without even doing the math.
C and D are clearly out, since the total is not 40 quarts.
Then, since equal amounts of 2% and 7% would results in (2+7)/2 = 4.5% fat, you clearly need more of the 7% fat. Thus, B is the only possible answer.
bruh this person said lawns. im dead bruh
The amount of quarts of 2% milk they need is 50 lawns.
LAWNS??
quarts of each type??
oops sorry the answers are
A. 24 quarts of the 2% milk and 16 quarts of the 7% milk
B. 16 quarts of the 2% milk and 24 quarts of the 7% milk
C. 16 quarts of the 2% milk and 16 quarts of the 7% milk
D. 24 quarts of the 2% milk and 24 quarts of the 7% milk
