Lana makes $8 an hour plus $12 an hour for every hour of overtime. Overtime hours are any hours more than 40 hours for the week.
Ierofanga [76]

Answer:

A:  W = 8x

B:  12y + 320

C:  44

Step-by-step explanation:

A:  Lana can make $8 an hour.

W = 8x

B:  She makes $12 per hour for every hour of overtime.  This means that she already worked 40 hours with regular pay.  She has already made $320.

40 × $8 = $320

S = 12y + 320

C:  Plug in the amount Lana earned into the second equation.  The second equation will account for pay from both regular and overtime hours.

S = 12y + 320

368 = 12y + 320

368 - 320 = (12y + 320) - 320

48 = 12y

48/12 = (12y)/12

4 = y

y = 4

Lana worked 4 hours of overtime and 40 hours of regular hours.  In total, she worked 44 hours.

4 + 40 = 44

Can someone answer and do the working out please!
trasher [3.6K]

Answer:

y=−4

Step-by-step explanation:

Let's solve your equation step-by-step.

7y−4=−32

Step 1: Add 4 to both sides.

7y−4+4 =−32+4

7y =−28

Step 2: Divide both sides by 7.

7y/7 = −28/7

y=−4

(/:divide) Hope it helps!!
