1. This farmer is selling pints of blueberries for \$3.50 a pint, or three pints for \$10. How much of a discount is the \$10 deal?

The farmer has discounted her produce by 50 cents. At \$3.50 a pint, three pints would cost \$10.50 without the discount.

3.50x3=10.50

10.50-10.00=.50

2. A customer has \$25. Rounded to the nearest whole pint, how many pints of blueberries can the customer buy?

A customer with \$25 can buy seven pints of blueberries, and still have \$1.50 left over. Using the discount, the customer can buy six pints of blueberries for \$20. One more pint is \$3.50. The customer has \$1.50 left over, not enough to buy another pint.

20.00+3.50=23.50

25.00-23.50=1.50

3. The same customer is determined to buy the maximum amount of blueberries for \$25. Rounding to the nearest hundredth, how many pints of blueberries can the customer buy?

With \$25, the customer can buy 7.43 pints of blueberries. Using the equation in Question 2, seven pints of blueberries cost \$23.50. By dividing the remaining amount the customer has left (\$1.50) by the price of a pint of blueberries (\$3.50), we can calculate that \$1.50 can buy .43 pint of blueberries.

1.5/3.5=.43
