Aldo is a software salesperson. His base salary is$2400 and he makes $90 more for every copy of English is Fun he sells. His total pay, p (in dollars), after selling c copies is given by the following.
P=2400+90c
Answer the following questions.
If Aldo's total pay is$5190 , how many copies did he sell?
What is Aldo's total pay if he sells 21 copies?
To find the number of copies Aldo sold, we can set up an equation using the formula for his total pay:
P = 2400 + 90c
We can plug in the given total pay of $5190:
5190 = 2400 + 90c
Subtracting 2400 from both sides of the equation gives:
2790 = 90c
Dividing both sides by 90 gives:
c = 31
Therefore, Aldo sold 31 copies.
To find Aldo's total pay if he sells 21 copies, we can again use the formula for his total pay:
P = 2400 + 90c
Plugging in c = 21 gives:
P = 2400 + 90(21)
= 2400 + 1890
= 4290
Therefore, Aldo's total pay if he sells 21 copies is $4290.
