Question

Linda is a software saleswoman. Her base salary is $1800, and she makes an additional $110 for every copy of Math is Fun she sells.Let P represent her total pay (in dollars), and let V represent the number of copies of Math is Fun she sells. Write an equation relating P to V. Then use this equation to find her total pay if she sells 28 copies of Math is Fun.

Answer 1

• P = 1800 + 110V

,

• $4880, for 28 copies

Step-by-step explanation

We have that P is Linda's total pay and V is the number of copies she sells.

We know that each copy of Math is Fun costs $110, so if she sells V copies the earnings will be $110*V. But she also has a base salary of $1800, so her total pay will be $110*V plus the base salary,

`P=1800+110V`

Now we have to find what is her total pay if she sells V = 28 copies. To do that, we only have to replace V for 28 in the equation above,

`P=1800+110\cdot28`

And solve,

`P=1800+3080=4880`

For 28 copies, her pay will be $4880.
