To find the amount that Andy spent on 10 toys, we have to multiply cost of each toy by 10.

Cost of each toy = $7.39

Amount that Andy spent on 10 toys = $7.39 × 10 = $73.90.

To find the amount that Jerald spent on 10 books, we have to multiply cost of each book by 10.

Cost of each book = $10.50

Amount that Jerald spent on 10 books = $10.50 × 10 = $105.00

In the pattern the number 25 is constant but the second number 10 is increasing 10 times in every subsequent product. In the last term, its value is 1000.

So, 1000 × 10 = 10,000.

The next multiplication sentence in the given pattern is 25 × 10000.

80 × 10 = 800 and 4 × 10 = 40

So, the missing numbers are 800 and 10.

Among the choices, 58 × 10 = 580

So, Pair 3 best completes the equation.

Among the choices, 76 × 100 = 7,600.

So, Pair 3 best completes the equation.

The product of 63 and 1,000 is 63 × 1,000 or 1,000 × 63.

So, the product of 63 and 1,000 is 63,000.

So, the value of 54 × 1,000 is 54,000.

So, 25 × 1,000 = 25,000.

1.23 × 10 = 12.30

2.525 × 1 000 = 2 525

To multiply a decimal by 100, move the decimal point two places to the right.

27.006 × 100 = 2 700.6

So, 115 × 100 = 11,500

Number of rows in the garden = 100.

Number of roses in each row = 22.

Number of roses in the garden = (number of rows) × (number of roses in each row)

= 100 × 22

= 2200

So, number of roses in the garden = 2200.
