Answer :
Gina is making $20 an hour.
She works 40 hours a week.
Without any raise she makes
[tex]\$20\times40=\$800[/tex]Now if she receives a 10% raise then
[tex]\$20\times0.10=\$2[/tex]So now she makes $20 + $2 = $22 an hour.
So with this raise, she will make
[tex]\$22\times40=\$880[/tex]How much more money will she make each week?
[tex]\$880-\$800=\$80[/tex]Therefore, Gina will make $80 more each week if she gets a raise of 10%
