Every week Perry gets paid $150 plus 12% of his total sales amount. Solve the equation 840=150+0.12(a−1,250) for a to find the total amount Perry must sell in order to be paid $840 in one week.

Respuesta :

Answer:

Step-by-step explanation:

840=150+0.12(a-1250)

840-150=0.12(a-1250)

690=0.12(a-1250)

690/0.12=(a-1250)

5750=(a-1250)

a=5750+1250

a=7000
