Two different memberships are available at a discount department store. The Type A membership costs $200 and allows you to enter the store and take 75% off the marked price. The Type B membership costs $50 and allows you to enter the store and pay 62.5% of the marked price. The equations and graph below describe the total cost in dollars, c, for each membership type that a person would spend on p dollars of merchandise. Type A membership: c = 0.25p + $200 Type B membership: c = 0.625p + $50
How many dollars worth of merchandise would a person have to buy for the cost of the Type A membership to equal the cost of the Type B membership?
please show how you got the answer
set the two different memberships equal to each other and solve for p: 0.25p + $200 = 0.625p + $50 (you might want to multiply both sides by 1,000 to get rid of the decimals)
250p + 200,000 = 625p + 50,000
thanks
if you got p = 400, you are right
thanks so much
