Mary’s yard is a mess. she needs to hire someone to prune her trees and shrubs. a landscaping service she calls quotes her a price of $15 consultation fee plus $8 an hour for the actual work. mary’s neighbor has offered to her out. she doesn’t charge a consultation fee, but does charge $10 an hour for her work. who do you think mary should hire for a 3-hour job? when, if at all, would it be more economical to hire the other service.

The person to hire for the 3-hour job is  Mary’s neighbor.

It would be economical to hire the other service at 7.50 hours.

In order to determine who should be hired, determine the total cost of hiring each individual.

Cost of hiring the landscaping service = consultation fee + total cost of three hours of work

$15 + $8(3) = $39

Cost of hiring Mary's neighbor = cost per hour x 3

$10 x 3 = $30

In order to determine when it would be economical to hire the  landscaping service, $15 + $8x = $10x

$15 = $2x

x = $7.50

She should ask her neighbor to help her.

Step-by-step explanation:

We can use equations to help us figure out this answer.

8x + 15 = y

10x = y

If she has a 3 hour job, we can use 3 instead of x.

8(3) + 15 = y

24 + 15 = y

30 = y for the landscaping service

10(3) = y

30 = y for a neighbors help

It will cost her 9 dollars less, so she should go with her neighbor.

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !
