Answer: 840 square inches
1. Split the figure into two rectangles.
2. Find x (there are other missing sides, but you do not need to know them).
x = 40 - 10
x = 30
3. Find the area of the two rectangles. Remember: A = lw.
Top rectangle: (10)(30) = 300
Bottom rectangle: (18)(30) = 540
4. Add the rectangles' areas together.
300 + 540 = 840

Answer:
1 $16.50
2 $28.50
3 $40.50
$4.50 + $12c
$100.50
Step-by-step explanation:
Please find attached the complete question
Total cost in dollars = fixed cost + (variable cost x number of CDs bought)
fixed cost = $4.50
variable cost = $12
number of cds bought = c
total cost in dollars = $4.50 + $12c
total cost in dollars when 1 cd is bought = $4.50 + $12(1) = $16.50
total cost in dollars when 2 cds are bought = $4.50 + $12(2) = $28.50
total cost in dollars when 3 cds are bought = $4.50 + $12(3) = $40.50
total cost in dollars when 8 cds are bought = $4.50 + $12(8) = $100.50
