5 0

Answer:

(95/31, -118/31)

Step-by-step explanation:

-7x-8y=9

4x+9y=-22

----------------

4(-7x-8y)=4(9)

7(4x+9y)=7(-22)

-----------------------

-28x-32y=36

28x+63y=-154

-----------------------

31y=-118

y=-118/31

-7x-8(-118/31)=9

-7x+944/31=9

-7x=9-944/31

-7x=279/31-944/31

-7x=-665/31

7x=665/31

x=(665/31)/7

x=(665/31)(1/7)

x=665/217=95/31

x=95/31, y=-118/31

One week Michael worked 40 hours and sold 2,870 worth of shoes if his employer paid him 12.50 per hour and 6% commission of all
liq [111]

Answer:

Money which Michael make in commission = 158.7

Step-by-step explanation:

Given that,

number of hours Michael worked in a week = 40 hours

total sale of the week = 2870

commission which Micheal will get on sale = 6% above 225sale

To find,

total money Michael make in commission in the week

Commission = (2870 - 225)*6%

Commission = (2870 - 225)*6/100

Commission = 2645 *6/100

Commission = 158.7

Total money Micheal make in a week = (40*12.50) + (158.7)

                                                                 = 658.7
