1. Suppose y is jointly proportional to x and z. What is y when x = 2 and z= 3, if y= 20 when x = 4 and z= 3?

2. Y varies directly as x and inversely as the square of z, and when x=32, y=6 and z=4. Find x when y=10 and z=3.

step-by-step explanation:

milk=16 large

soda=280 kids

juice box=82 regular

63 soda +63 regular

124 large total

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.
