Answer:
He will make $88 more per week with the raise.
Step-by-step explanation:
Since we are asked about the increment, we focus on finding the amount of money he has gained from raise, once we have that we can find the total amount gained per week, knowing he works 40 hours per week.
Raise increment in dollars.
Since he has a raise of 10%, we can find the value of 10% of $22 first.
[tex]\text{ Increment per hour } = \$22(0.1)[/tex]
Notice that we have to multiply to find that increment and we are writing 10% in decimal form, that is 0.1, so we get:
[tex]\text{ Increment per hour } = \$2.2[/tex]
Total amount gained per week
We know that he makes now $2.2 per hour, so in 40 hours, he will make:
[tex]\text{ Increment per week } = \$2.2\text{ per hour} \times 40 \text{ hours per week}[/tex]
That give us
[tex]\text{ Increment per week } = \$ 88[/tex]
Thus the increment per week is $88.
