**Answer:**

14 shirts

**Step-by-step explanation:**

11-4= 7

7 times 2 = 14

Volume formulas:

rectangle prism: l×w×h

cube: s^3

cylinder:(pi)r^2×h

triangle prism: (a×b/2)×h

cylinder:(pi)r^2×h

box:l×w×h

40) 5m×3m×4m =15m×4m= 60m^3

41) 6 ft × 6 ft ×6 ft = 36 ft × 6 ft = 216 ft^3

42) d=2r 10/2=5 r=5

3.14×5^2×14=78.5×14= 1099cm^3

43) 15=a×b/2 (area of trianlge)

15×12= 180in^3

44) c=2 (pi)r 8pi=2r (pi)

r=4

3.14×4^2×7=50.24×7=351.68

45) 24 ft^3 =2 ft × 3 ft × height

24=6×h

÷6 both sides

h=4ft

**Answer:**

**Step-by-step explanation:**

gift + lunch + (skittles * count) ≤ $21

9.25 + 3.50 + 0.40x ≤ 21

12.75 + 0.40x ≤ 21

0.40x ≤ 8.25

**x ≤ 20.625**
