Answer: [tex]\$3,740[/tex]
Step-by-step explanation:
You know that Josh's base salary is:
[tex]base\ salary=\$2,200[/tex]
And, according to the information given in the exercise, Josh makes $70 more for every copy he sales.
Knowing this you can determine that his total pay will be the sum of his base salary and the podruct of $70 and the number of copies.
Therefore, if Josh sells 22 copies, then we get that his total pay is:
[tex]Total\ pay=\$2,200+(22)(\$70)\\\\Total\ pay=\$3,740[/tex]
