- 1. 1. $7.25
2. Ohio and it’s $7.70
3. Nevada $8.25
4. 7.25(h)
5. y-=7.25n+t
N=10 t=tips
7.25(10)+15
72.50+15=$87.50
N=the number of hours worked in a week.
6. s=sum of earnings
R= hours worked (10)
x= rate of pay (17.25)
y=rich’s rate of pay (17.25)
T=tips (15.00)
R(x)+r(y)+t=s
10(x)+10(y)+tips=s
1(7.25)+10(7.25)+15=s
72.50+72.50+15=$160.00
- 2. 7. d= diff in wages
H=hours I worked (10)
N=hours rich worked (10)
T=tips rich earned (15.00)
(7.25n+t)-(7.25h)=d
[10(7.25)+15]-[(7.25)10)=d
87.50-72.50=d
15.00=d
8. T= total earned (80.00)
X= number of hours worked (10)
B=bonus(20.00)
X(7.25+.50)+b=t
x(7.75)+20.00=80.00
7.75x=80.00-20.00
7.75x=60.00
60 = 7.7
7.75
- 3. 9. x= number of hours I and rich worked
B= riches bonuses (20.00)
7.25x+20.00=7.75x
20.00=7.75x-7.25x
20.00=.50x
20.00 =X
x.50
40 hours =x
- 4. 10. 95=7.25x+15
-15 -15
80=7.25x
7.25 7.25
X=11.03
