What is the final amount if 2250 is decreased by 2% followed by a further 3% decrease?
Marrrta [24]

Answer:

2138.85

Step-by-step explanation:

2250 decreased by 2% is

2% of 2250 subtracted from 2250

That’s

2% /100% x 2250

0.02 x 2250

45

So, decrease = 2250 - 45

= 2205

Now 2205 decreased by 3%

3% of 2205

3% /100% x 2205

0.03 x 2205

66.15

Decrease = 2205 - 66.15

= 2138.85

A carpenter charges $720 for 18 hours of work. She charges the same amount of money for each hour of work.
Rainbow [258]

Answer:

A

Step-by-step explanation:

To start off, you know 18 hours= 720

So you could automatically get rid of B and D since 19 and 17 are not 18.

After that, you have it down to A and C. The way you would find how much she charges for one hour is dividing 720 by 18. When you do that it means you are divding 720$ into 18 different groups each group representing an hour. When you divide 720 by 18 you should get 40. So every hour she makes 40 dollars. 40x 2 hours is 80. I hope I helped you!
