Size 40 is the cheapest, because the formula to find lowest price of unit is dividing the price by the unit. so 5.49/24≈ 0.23, 8.00/40=0.2, 15.99/64≈ 0.25
Answer:

Step-by-step explanation:
-4.4(s - 2) + 6.9s = 14.8
Distribute -4.4 into the parenthesis:
-4.4s + 8.8 + 6.9s = 14.8
Combine like terms:
2.5s + 8.8 = 14.8
Subtract 8.8 from both sides of the equation:
2.5s + 8.8 - 8.8 = 14.8 - 8.8
2.5s = 6
Divide both sides by 2.5:
2.5s/2.5 = 6/2,5
s = 2.4
s =
