Answer:
A: Â W = 8x
B: Â 12y + 320
C: Â 44
Step-by-step explanation:
A: Â Lana can make $8 an hour.
W = 8x
B: Â She makes $12 per hour for every hour of overtime. Â This means that she already worked 40 hours with regular pay. Â She has already made $320.
40 × $8 = $320
S = 12y + 320
C: Â Plug in the amount Lana earned into the second equation. Â 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. Â In total, she worked 44 hours.
4 + 40 = 44
