Answer 1

To find equivalent prices to the advertised cost of 15 cups of granola for $6.75, divide the total cost by the number of cups.

The equivalent prices are 2 cups for $0.90, 8 cups for $3.60, and 19 cups for $8.55.

Therefore, the correct options are:

2 cups for $0.90
8 cups for $3.60
19 cups for $8.55.

Step-by-step explanation:

To determine which prices are equivalent to the advertised cost of 15 cups of granola for $6.75, we can divide the total cost by the number of cups.

First, let's find the cost per cup:

$6.75 ÷ 15

= $0.45 per cup.

Now let's check the given prices:

• 2 cups for $0.90: $0.90 ÷ 2 = $0.45, equivalent price
• 5 cups for $2.45: $2.45 ÷ 5 = $0.49, not equivalent price
• 8 cups for $3.60: $3.60 ÷ 8 = $0.45, equivalent price
• 10 cups for $4.05: $4.05 ÷ 10 = $0.41, not equivalent price
• 19 cups for $8.55: $8.55 ÷ 19 ≈ $0.45, equivalent price
• 25 cups for $11.75: $11.75 ÷ 25 = $0.47, not equivalent price

The equivalent prices are:
2 cups for $0.90
8 cups for $3.60
19 cups for $8.55.
