Job A: $15.00 per hour (40 hours a week)​​Job B: $1,375 semi-monthly
blagie [28]

Notes before we start:

Semi-monthly means you get paid twice a week. We will find out the net pay in 2 weeks to see how much pays better.

Explanation:

Job A pays $15 an hour and whoever is working works 40 hours a week. We can multiply to find how much he/she earns in 2 weeks.

15 * 40 * 2 = $1,200

Job B pays $1,375 semi monthly which means that he/she got paid that much money in 2 weeks.

Answer:

Job B pays better.

Best of Luck!

Blababa [14]
-2(1+2x)=7-x
-2(1)=-2 -2(2x)=-4x rewrite
-2-4x=7-x combine like terms add two to both sides 7+2=9; add x to both sides -4x+x=-3x rewrite -3x=9 divide -3 from both sides 9/-3=-3 rewrite
X=-3
