B. 26. 15%
C. 35.42%
D. 73.85%

35.42%

Step-by-step explanation:

C. 35.42%

Step-by-step explanation:

65 - 48 = 17

Since he grew 17 inches, you must figure out what percentage 17 is of 48.

17/48 = 1/100 (represents decimal)

Cross multiply: 17 ⋅ 100 = 1700 and 48 ⋅ 1 = 48

Divide: 1700/ 48

= 35.41666666666667

Round to the nearest hundredth:

= 35.42

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
