Answer 1

The cost of any number of 8x10 photos is twice the cost of the same number of 5x7 photos, which makes statement B true according to the cost table provided. Therefore, statement A is true A. The cost of any number of 8 x 10 photos is $1 more than the cost of the same number of 5 x 7 photos.

Step-by-step explanation:

The question asks to determine which statement is true regarding the cost of 5x7 and 8x10 photo prints based on the given data. To solve this, we compare the price of each size and see how they relate to each other.

For a 5-inch x 7-inch photo, the cost is $1 per print. For an 8-inch x 10-inch photo, the cost is $2 per print. According to the table:

• 1 photo costs $1 (5x7) and $2 (8x10)
• 2 photos cost $2 (5x7) and $4 (8x10)
• 3 photos cost $3 (5x7) and $6 (8x10)
• 4 photos cost $4 (5x7) and $8 (8x10)

The table shows the cost of buying some photos, with the cost of 5x7 photos and 8x10 photos increasing by $1 for each additional photo.

From the table, it is clear that the cost of any number of 8x10 photos is $1 more than the cost of the same number of 5x7 photos. Therefore, statement A is true A. The cost of any number of 8 x 10 photos is $1 more than the cost of the same number of 5 x 7 photos.
