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:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
