Question

Find the discount, the discount rate, and the reduced price for a box of cereal that normally sells for $3.29 if a shopper presents the coupon at a store that doubles the value of the coupon. (Round the discount rate to the nearest one percent.)

the savings of the cereal is 35 cents.

discount $



discount rate %

reduced price $

Answer 1

The discount is the reduction in price so it is 35 cents x 2 (double value) which is $0.70.

The discount rate is the percentage of the discount so it is the discount divided by the regular price or $0.70/$3.29 = 0.2128. To turn a decimal into a percent, multiply by 100 so 0.2128 = 21.28% or, in this case, since we are rounding to the nearest percent, 21%

The reduced price is the regular price minus the discount so $3.29 - $0.70 = $2.59
