Answer:
total earning is $64.80
Step-by-step explanation:
Price of one work = $18.00
Payment by owner = 1/4 of $18.00
= 18/4
= $4.50
Earning by tip = 20% of $18.00 = 20/100 x18 = 3.60
Total earning from one work = $4.50+$3.60
= $ 8.10
Earning from 8 tips = 8x8.10
= $64.80
4(y-3) = 4*y -4*3
= 4y - 12
Answer:
52%
Step-by-step explanation:
5+8+12=25
5+8 or red+blue= 13
13/25= 52%
Answer:
It will take 56 years to make $100,000
Step-by-step explanation:
We can use the expression for the future value to determine the number of years you will work to make $100,000. The expression is as shown;
FV=PV(1+r)^n
where;
FV=future value of salary
PV=present value of salary
r=annual raise in salary
n=number of years
In our case;
FV=$100,000
PV=$50,000
r=1.25%=1.25/100=0.0125
n=unknown
replacing;
100,000=50,000(1+0.0125)^n
100,000/50,000=(1+0.0125)^n
2=1.0125^n
ln 2=ln 1.0125^n
ln 2=n ln 1.0125
n=ln 2/ln 1.0125
n=55.7976 rounded up=56
It will take 56 years to make $100,000
