Question

Johnny is buying watermelons. Safeway is running a sale where all watermelon

purchases are $15 off the final price and each watermelon costs $3.50. Write a linear
equation that models this scenario.

Answer 1

3.50x-15= y

Reason:

In the equation y would be the total price and x would be the amount of watermelons. The slope is 3.5- and the y intercept is -15.

y = mx + b

m/slope = 3.50

b/y-intercept = -15

x = amount of watermelons

y = total cost
