Step-by-step explanation:
LAST ONE
The answer is A $525
He earns $300 a week
The sales for one week are $2500
Percentage of commission on sale above $1000= 15%
[2500-1000]*(15/100)
=1500*(15/100)
=15*15 dollars
=$225
Then Gross pay of Edgar Anderson for the week = (300+225)dollars
=$525
20+8q -88= -12
8q -68 = -12
8q = 68-12
8q = 56
q= 56/8
q= 7
