Answer:
Number of strawberry plants not infested with bugs = 24
Explanations:
The number of Strawberry planted by Mrs. Torres = 30
20% of the plants were infested with bugs in April
Number of Strawberry infested with bugs = 20% of Strawberry planted
Number of Strawberry infested with bugs = 20% of 30
Number of Strawberry infested with bugs = (20/100) x 30
Number of Strawberry infested with bugs = 0.2 x 30
Number of Strawberry infested with bugs = 6
Number of Strawberry not infested = Total Strawberry - Number of strawberry infested
Number of Strawberry not infested = 30 - 6
Number of Strawberry not infested = 24
