Answer:
The answer is C.
Step-by-step explanation:
825-735 is 90.
830-755 is 75.
90-75 is 15 meaning Drew beat Kurt by 15 minutes.
1 pound = 16 ounces
16 * 5.5 = 88 ounces per day
88*7 = 616 ounces per week
616 * 2 = 1232 ounces in 2 weeks
X = 1 hr lessons and y = 1/2 hr lessons
x + y = 35......y = 35 - x
40x + 25y = 1115
40x + 25(35 - x) = 1115
40x + 875 - 25x = 1115
40x - 25x = 1115 - 875
15x = 240
x = 240/15
x = 16 <=== there are 16 one-hr lessons
and 19 half-hr lessons
That would be : y = 2x + 1
He used an incorrect time ratio converting hours to minutes.
