66,000*0.15
9,900*5
49,500+66000
The answer is 115.500
I'm not sure if the whole thing is correct, but here is the easier way:
66,000(1+1.15)^5
2) Inserting zeros at the right end of a decimal does not change its value
0.3 = 0.3000
4) To estimate the difference between 0.31 and 0.108, subtract 0.3.
22) 75.285 + 2 + 3.871 + 0.5 = 81.656
42) 0.01 - 0.0001 = 0.0099
50) 9 - 4.63 = 4.37
Six thirty-five...............................
20% of 850 was paid in cash..
0.20(850) = 170 was paid in cash
so (850 - 170) = 680 was not paid in cash
Divide the number of questions she got correct by the total number of questions on the test them multiply the decimal answer by 100 to get the percent.
42/60 = 0.7
0.7 x 100 = 70%
