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.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
