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.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

the answer is b.)
