the answer is c..................

Answer 2

C. She added 10.5 and 50, then multiplied by 6 to calculate the amount earned for 6 hours.

Explanation:

Sherry earns an hourly wage plus a bonus for each day’s work.

She uses the equation
`10.5h+50` to represent the total amount she earns each day, where h is the number of hours she works.

Lets check the equation for each hour.

For 1 hour:

`10.5(1)+50`

=>
`10.5+50=60.5` dollars (correct)

For 2 hours:

`10.5(2)+50`

=>
`21+50=71` dollars (correct)

For 4 hours:

`10.5(4)+50`

=>
`42+50=92` dollars (correct)

For 6 hours:

`10.5(6)+50`

=>
`63+50=113` dollars (wrong)

So, the 6 hours calculation is wrong.

Therefore, C is the right answer.

C. She added 10.5 and 50, then multiplied by 6 to calculate the amount earned for 6 hours.
