Ean Haynes · Answer 1

5q + 2d = 270

The intercepts can be calculated by first putting d equal to 0 and then q equal to 0. These will be:

5q = 270

q = 54; (0, 54)

2d = 270

d = 135; (135, 0)

The equation represents the total number of coins in the piggy bank and (0, 54) shows the number of quarters in the piggy bank when there are no dimes and (0, 135) shows the number of dimes when there are no quarters.
