Length = x
width = y
2x + 2y = 32
x - y = 4
x = 4 + y
2(4+y) + 2y = 32
8 + 2y + 2y = 32
4y = 24
y = 6 cm (width)
x = 4 + 6
x = 10 cm (length)
There's two ways to do this problem: y=mx+b and normal division. To divide, just do 390 ÷ 40 and 234 ÷ 24. Both equations should equal 9.75. The other way is a bit more complicated, but it's the way I solved it. They give you two points, (24,234) and (40,390). 10 is b, now to find the slope. To find the slope you do y2-y1 over x2-x1. Plug the numbers in: 390-234 over 40-24. Simplify: 156/6, which equals 9.75. So, y=9.75x+10. The answer is: after 10 hours of work, she'll make $9.75

Answer:Jake's total cost is $22.05
Step-by-step explanation:
The initial price of the sweater is $30. The store is having a sell that will reduce the price by 30%. This means that there is a reduction in the original amount of the sweater by 30% which is expressed as
30/100 × 30 = $9
The new price of the sweater would be 30 - 9 = $21
Since a sales tax of 5% will be added to the final purchase price, the value of the tax would be
5/100 × 21 = 0.05×21 = $1.05
Jake's total cost would be
21 + 1.05 = $22.05
