Andy is buying a new laptop computer. the store is offering a 15% discount on the model he wants. andy also has a certificate from the manufacturer good for $120 off his next computer purchase. write the composite function showing the certificate being applied after the discount. what will andy pay for a computer that costs $1199.00?

$899.15

0.85(1199) - 120

Step-by-step explanation:

To find the purchase total, multiply the price by the percent paid and subtract the certificate.

The store offers a 15% discount. This means you pay 85% of the price. So the discounted price is 0.85(1199) = 1019.15

Subtract the certificate 1019.15 - 120 = 899.15

The composite function is 0.85(1199) - 120.

0.6

39mph

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
