Chris sells cars and he get a salary of 6.00 per hour plus a 0.9% commission. one week he work 32 hours and sells 2 cars priced at 26,700 and 31,150.how much did he make that week

Earnings of Chris that week = US$ 712.65

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Chris' salary = US$ 6 per hour + 0.9% commission (0.009)

A week Chris worked 32 hours and sold 2 cars priced $ 26,700 and $ 31,150

2. How much did he make that week?

Earnings of Chris that week = (32 * 6) + (26,700 * 0.009) + (31,150 * 0.0009)

Earnings of Chris that week = 192 + 240.30 + 280.35

Earnings of Chris that week = US$ 712.65

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
