year 1
cost = 1.03 (1500) = 1545
put 1545 in for x in year 2
year 2
1.03 * 1545 = 1591.35
put in 1591.35 in for x in year 3
year 3
1.03 *1591.35=1639.0905
round to the nearest cent
cost in three years: $1639.09
Choice C
Alright, the first thing we should have to do is find the total cost per year of his insurance. To do that, we multiply $96.21 by the 12 months in a year to get $1154.52. This is the cost of his insurance per year.
Next, we need to find out how much his boss covers, which we know is 85% of the total cost. SO what we can do is multiply the yearly cost ($1154.52) by the percent his boss covers (.85) to get $981.342. This is how much his boss covers per year.
Lastly, to find out how much Derek pays for insurance yearly, we just need to subtract how much his boss pays ($981.342) from the total yearly cost ($1154.52), which leaves us with $173.178, which is how much Derek pays yearly for his insurance, which should be your answer.
Answer:
876 square feet need to be painted.
Step-by-step explanation:
There are four walls in each bedroom, since she can't paint floors or ceilings. So we calculate the number of square feet of wall there is in one bedroom
(12*8)+(12*8)+(10*8)+(10*8)-60=160+192-60=292
There are 3 bedrooms so
292*3=876
