Answer :

Sure, let's solve these problems step-by-step.

Question 4: How much will 27 slices of pizza cost?

1. A single slice of pizza costs [tex]$1.57.
2. We want to find the cost of 27 slices.

To find the total cost, we multiply the cost of one slice by the number of slices:
\[ \text{Total cost} = 1.57 \times 27 = 42.39 \]

So, the cost of 27 slices of pizza is $[/tex]42.39.

Question 5: A spool of ribbon holds 6.75 meters. A craft club buys 21 spools.

a. What is the total cost if the ribbon sells for [tex]$2 per meter?

1. Each spool of ribbon is 6.75 meters long.
2. The craft club buys 21 spools.

First, we need to find the total length of the ribbon:
\[ \text{Total length} = 6.75 \times 21 = 141.75 \, \text{meters} \]

Now, we need to find the total cost, given that the ribbon sells for $[/tex]2 per meter:
[tex]\[ \text{Total cost} = 141.75 \times 2 = 283.5 \][/tex]

So, the total cost if the ribbon sells for [tex]$2 per meter is $[/tex]283.50.
