A user car dealer brought a car for $12,000 and wants to sell it at a 15% profit. How much should he sell the car for?

Snezhnost [94]

Answer:

$13,800

Step-by-step explanation:

She sells the car for 115% of the value of the car, because she wants a 15% profit. 115% of 12000 is the same as 12000*1.15, since 115% is eqaul to 1.15. 12000*1.15 = 13800

Answer:

3.5(1.6 + 4.6 - 8.5) - 9.75
= 3.5(-2.3) - 9.75
= -8.05 - 9.75
= -17.8

Step-by-step explanation:

1.6 + 4.6 - 8.5 = -2.3
3.5(-2.3) = 3.5 × -2.3 = -8.05
-8.05 - 9.75 = -17.8

I hope this helps!
