Bill worked 24 hours last week and earns $8.25 per hour. use front-end estimation to find an estimate of the total amount of money he earned.

The total amount of money he earned was $160

Step-by-step explanation:

Bill worked 24 hours last week

He earns $ 8.25 per hour.

We have to use front-end estimation, we have to round to the first number all the values. So. Bill worked h = 20 hours and he earns 3 =$8 per hour.

Total amount (T) wil be the hours (h) multiplied by the earning (e)

T = h*e

T = (20 hours)(8 $/hours)

T = 160 $

After using front-end estimation, we can conclude that Bil earned $160.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
