Apolline is mowing lawns for a summer job. For every mowing job, she charges an initial fee plus a constant fee for each hour of

OLEGan [10]

Answer:

Base Fee = $7

Extra charges = $7

Step-by-step explanation:

Represent the base charge with x and the additiional charges with y.

For the 5 hours job, we have:

$42 = x + 5y$

For the 3 hour job

$28 = x + 3y$

Solving for x and y;

$42 = x + 5y$

$28 = x + 3y$

Subtract the second equation from the first

$42 - 28 = x - x + 5y - 3y$

$14 = 2y$

Solve for y

$y = 14/2$

$y = 7$

Substitute 7 for y n the first equation

$42 = x + 5y$

$42 = x + 5 * 7$

$42 = x + 35$

$x = 42 - 35$

$x = 7$

dem82 [27]

Answer:

5 miles

Step-by-step explanation:

An hour and 25 minutes is 85 minutes. Using the given information we can find the distance d with the proportion ...

$\dfrac{\text{distance}}{\text{time}}=\dfrac{d}{85\text{ min}}=\dfrac{1\text{ mi}}{17\text{ min}}\\\\d=\dfrac{85\text{ min}}{17\text{ min}}(1\text{ mi)}\qquad\text{multiply by $85$ min}\\\\d=5(1\text{ mi})\qquad\text{simplify}\\\\d=\boxed{5\text{ mi}}$

In 1 hour and 25 minutes, Nick will travel 5 miles.
