Answer:

3.5 inches

Step-by-step explanation:

Set up a proportion:

\frac{9 ft}{1 in} = \frac{31.5 ft}{x in}

Cross multiply in order to solve for x:

9x = 31.5

Divide by nine:

x = \frac{31.5}{9}

Simplify:

x= 3.5

Brand X copier advertises that its copiers run 24% longer between service calls than its competitor. If Brand X copiers run 59,8
Alexus [3.1K]

Answer:

The competitor will run 48,225.81 copies.

Step-by-step explanation:

Brand x copier run 59,800 copies between services

Brand X copiers run 24% longer between service calls than its competitor.

Let x = copies run by the competitor between services

Number of copies the competitor will run is

24% of x + x = 59,800

0.24x + x = 59,800

1.24x = 59,800

x= 59,800 / 1.24

x = 48,225.81

Therefore, the competitor will run 48,225.81 copies.
