Teresa is a software engineer. Her base salary is $2400 and she makes $80 more for every copy of “Math is Fun”. Her total pay , P, (in dollars), after selling c copies is given by the following function. P(c) = 2400 + 80c

1. What is Teresa’s total pay if she sells 22 copies?

2. If Teresa’s total pay is $5040, how many copies did she sell?

1.) Teresa’s total pay if she sells 22 copies is $4160.

2.) If Teresa’s total pay is $5040, then she sold 33 copies.

Step-by-step explanation:

Teresa’s total pay if she sells 22 copies

P(c) = 2400 + 80c

P(22) = 2400 + 80(22) = 1760

P(22) = 2400 + 1760

P(22) = $4160

Thus, Teresa’s total pay if she sells 22 copies is $4160.

If Teresa’s total pay is $5040, how many copies did she sell?

Here,

Total pay – Teresa's salary = total pay after selling copies

$5040 – $2400 = $2640

Now, we know that she paid $80 for making every copy.

So,

2640 ÷ 80 = 33

Thus, If Teresa’s total pay is $5040, then she sold 33 copies.

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

tip $2.90

total $17.40
