Jason runs the same distance each day. In one 7-day period he ran 40 1/4 miles. He knows that there is a proportional relationship between n, the number of days, and t, the total distance he runs. Tell whether each statement is True or False. A. The relationship can be expressed as n=5.25t. True or False
B. The graph of the equation is a straight line through (0,0). True or False
C. The unit rate is 5.75. True or False

A. The relationship can be expressed as n=5.25t. True or False
B. The graph of the equation is a straight line through (0,0). True or False
C. The unit rate is 5.75. True or False

The answer is A

We can set up equations to help us out

8x + 15= y

10x=y

If she has a 3 hour job, we can plug 3 in for x to find out which is better

8(3) + 15=y
24 + 15= y
39=y for a landscaping service

10(3)=y
30=y for a neighbors help

Since it will cost her 9 dollars less, she should go with the neighbor
