The monthly dues for a premium membership at a health club is $15 more than the cost of a standard membership. The premium member is $40. Write and solve an equation to find the cost of a standard membership. Use the variable x.

Step-by-step explanation:

40-15=x

25=x

check

25+15=40

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
