Respuesta :
The family should purchase the 4 boxes for 6 dollars to spend a lesser amount of money. They will save $4.
Answer:
Step-by-step explanation:
To solve the given question we will find the price of 24 boxes using different rates of the boxes.
"If the rate is 3 boxes for 5 dollars."
∵ 3 boxes costs = $5
∴ 1 box costs = [tex]\frac{5}{3}[/tex]
∴ 24 boxes costs = [tex]\frac{5\times 24}{3}[/tex]
              = $40.00
"If the rate is 4 boxes for 6 dollars"
∵ 4 boxes costs = $6.00
∴ 1 box will cost = [tex]\frac{6}{4}[/tex]
∴ 24 boxes will cost = [tex]\frac{6\times 24}{4}[/tex]
                 = 6 × 6
                 = $36
Therefore, snacks of 4 boxes for $6 will be economical and amount saved 40 - 36 = $4.00
