Question

A chef buys 9 cucumbers, 18 peppers, and 21 tomatoes at the farmer's market. How much does she spend

Shop cucumber 6 for $2 peppers 12 for $9 tomatoes for 6 for $4

Answer 1

The price is multiplied by the fraction: (number bought)/(number included in the price). The total amount spent is the sum of amounts spent on each item.

... (9/6)×$2 + (18/12)×$9 + (21/6)×$4 = $3 + 13.50 +14.00 = $30.50
