Actually, she worked for seven hours, so I'll solve for that.
7.20 x 3 = 21.6
6.75 x 4 = 27
21.6 + 27 = 48.6
48.6 /2 = 24.3
Her average should be $24.3 If she did work six hours, just multiply 6.75 x 3 and do what I did.
Step-by-step explanation:
1)ab-c
=2(3)-4
=6-4
=2
2)6c-2b
=6(4)-2(3)
=24-6
=18
3)a+b-c+5
=2+3-4+5
=10-4
=6
5)7c-2a
=7(4)-2(2)
=28-4
=24
