Question

Sylvia's plant was 5 inches last week. This week it grew to 6 inches. What is the percent of increase in the height of the plant?

a) 10%
b) 15%
c) 20%
d) 25%

Answer 1

The percent increase in the height of Sylvia's plant is found by dividing the difference in height (1 inch) by the original height (5 inches) and then multiplying by 100, resulting in a 20% increase.

Step-by-step explanation:

The student is asking about the percent increase in the height of Sylvia's plant. To calculate the percent of increase, we need to follow these steps:

1. Find the difference in height by subtracting the original height from the new height. In this case, 6 inches (new height) - 5 inches (original height) = 1 inch.
2. Divide the difference by the original height: 1 inch / 5 inches = 0.20.
3. Multiply this result by 100 to find the percentage: 0.20 x 100 = 20%.

Therefore, the correct answer is c) 20%.
