Question

00:00 Dagne measures and finds that she can do a vertical jump that is 27.5% of her height. If Dagne can jump 13.2 inches, how tall is she? inches

Answer 1

Let x be her height

27.5% of x = 13.2

$\frac{27.5}{100}\times x=13.2$$\frac{27.5x}{100}=13.2$

Multiply both-side of the equation by 100

$27.5x\text{ = 1320}$

Divide both-side of the equation by 27.5

$x=48$

Hence, she is 48 inches tall
