Achef buys 9 cucumbers,18 peppers,21 tomatoes at the farmer's market. how much does she spend?

cucumbers 6 for $2
peppers 12 for $9
tomatoes 6 for $4

$30.50

Step-by-step explanation:

9 cucumbers- 6=$2

9-6=3, is half of 6 so it would be half the price so $1. $2+$1=$3 total for cucumbers

18 peppers- 12=$9

18-12=6, is half of 12 so it would be half the price so $4.50. $4.50+$9=$13.50

21 tomatoes- 6=$4

6•3=18=$12, 21-18=3, is half of 6 so it would be half the price so $2. $12+$2=$14
