Answer:
7a) The slope of the line is (simplified) 1/2, and this represents the number of berries Kaley should depending on the amount of Yogurt.
7b) Kaley should use 18 berries. If she uses 2 berries per 1 cup of yogurt, then you would multiply that by 9.
8) Heidi ran 2/3 laps per minutes, not 3/2. The mistake she made was by putting x over y, not y over x.
Answer:
5 hours
Step-by-step explanation:
Set up an equation where y=total cost and x= hours
y=7x+15
Substitute 50 for y, the total cost, and solve for x, the total hours
50=7x+15, Subtract 15 from both sides
35=7x, Divide both sides by 7 to get x alone
x=5
