Question

If fuses cost $2.35 each, and each motor requires 3 fuses, how many motors can be supplied with $493.50 worth of fuses?

Answer 1

From the statement we know that:

• fuses cost $2.35,

,

• a motor requires 3 fuses, so it requires Cm = 3 * $2.35 = $7.05 of cash for the fuses,

,

• we have $493.5 of cash to invest.

So the amount of motors that we can supply is:

$\frac{493.5}{C_m}=\frac{493.5}{7.05}=70$

Answer

We can supply 70 motors.
