Jim makes $8.50 an hour. each week 26% of his total pay is deducted for taxes how many hours does he have to work to earn at least $300 per week

Answer-

Jim has to work 48 hours to earn at least $300 per week.

Solution-

The amount Jim earns per hour = $8.50 and 26% of his pay is deducted for taxes.

Suppose he works x hours per week, so he will be earning in a week = 8.50x

Then, the amount he will pay for taxes = 26% of 8.50x = (0.26)(8.50)x

After tax deduction, the amount that he will be left with = 8.50x - (0.26)(8.50)x

And he has to work in order to get $300 per week after tax deduction,

So,

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
