If Jasper installs a floor himself, it will take him 7 hours. Working with Yolanda, it will take them 3 hours.

Svetllana [295]

Answer: 5 $\frac{1}{4}$ hrs

<u>Explanation:</u>

Jasper: $\frac{1}{7}$ per hr

Yolanda: $\frac{1}{x}$ per hr

Together: $\frac{1}{3}$ per hr

Jasper + Yolanda = Together

$\frac{1}{7}$ + $\frac{1}{x}$ = $\frac{1}{3}$

$(21x)\frac{1}{7}$ + $(21x)\frac{1}{x}$ = $(21x)\frac{1}{3}$

3x + 21 = 7x

21 = 4x

$\frac{21}{4}$ = x

$5\frac{1}{4}$
