Answer:
52
Step-by-step explanation:
(-6)x(-6)=36
(4)x(4)=16
36+16=52
(12 x 2) - 5 because twice as many means to multiply by 2. fewer means to subtract.
we have that
the total cost is

In this equation the term 30h represent the cost due to h hours at at unit of 30
and the term 0.040(30h) is equal to calculate the 4% of (30h)
