Assume that you want to replace your sailboat with a larger one in 3 years. To save for a down payment for this purchase, you deposit $2,000 for 3 years in a bank account that pays
10% annual interest, compounded annually. How much will be in the account at the end of 4
years?

$11,600

Step-by-step explanation:

$2000 * 10% = $200

y = 200x + $2,000

12 * 4 = 48

48 = x

y = 200(48) + $2,000

y = $9,600 + $2,000

y = $11,600

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
