Brett plays an acoustic guitar at an event for $500. At the end of the event, the sponsor tips him 20%. How much does Brett make at this event?

$600

Step-by-step explanation:

Tip: 20% is .2 or 1/5

500 × .2 = 100.

500 + 100 = 600

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.'
