Answer:6
Step-by-step explanation:
(86,400 cubic inches) x (1 cubic foot / 1,728 cubic inches) = 50 cubic feet
<u>Part A : </u>
W = 8x
-
<u>Part B : </u>
S = 8x + 12y
-
<u>Part C: </u>
S = 8x + 12y
-
Since 368 is more than 8 x 40, she must have worked more than 40 hours:
368 = 8(40) + 12y
368 = 320 + 12y
12y = 368 - 320
12 y = 48
y = 48 ÷ 12
y = 4
-
Total hours worked = 40 + 4 = 44
-
Answer: She worked 44 hours
