SO he earned 755 approximately
To start off, 5/25 is 1/5. 25 and 5 can both be divided by 5, thus it is 1/5 smiplified. Now you add 12 and it is 12 and 1/5.
Answer:
$0.43
Step-by-step explanation:
Rate of increase = [(CPI in 1990 / CPI in 1980)^1/t] - 1
(130.7 / 82.4)^1/10
1.586165^0.1 = 1.047213 - 1 = 4.72%
Price of dish soap in 1990 = value in 1980 ( 1 + rate of increase)^10
0.74( 1.047213)^10 = 1.174
Price increase 1.174 - 0.74 = 0.43
Answer: 22
Step-by-step explanation:
The Answer is A
5x=85 (to find the x get the x alone so divide 5 from 5x and also do the same on the other side with 85)
112=4y+4 (minus 4 from 4y+4 and minus 4 on the other side as well with the 112, 112-4=108
108=4y (get the y by itself so divide 4 from 4y and divide 4 from 108 as well, 108/4= 27)
