Number 2 is 84.13
number 4 is 56
8.75%
25x1.5=37.5
40.78/37.5= 1.0875
Subtract the 1 off for the product cost and it leaves 0.0875 for the tax
JoAnn would have worked 45 hours. You start by multiplying 13 and 35 and subtract that from 650 to get 195. from there you d8ivide 195 by 19.50 to get 10. Lastly, you add 35 and 10 to get a total of 45 hours
Assume that
a and b = the two legs of the right triangle.
c = the hypotenuse.
The area of the right triangle is 750 yd², therefore
(1/2)*a*b = 750
ab = 1500 (1)
The perimeter is 150yd, therefore
a + b + c = 150 (2)
Let the side fenced with wood be a, at $5/yd. Sides b and c are fenced with steel at $10/y. The total cost is $1200, therefore
5a + 10b + 10c = 1200
or
a + 2b + 2c = 240 (3)
From (2), obtain
c = 150 - a - b (4)
Substitute (4) into (3)
a + 2b + 2(150 - a - b) = 240
-a + 300 = 240
a = 60
From (1), obtain
60b = 1500
b = 25
From (4), obtain
c = 150 - 60 - 25 = 65
Answer:
A. The length of the leg fenced with wood is 60 yd.
B. The length of the leg fenced with steel is 25 yd.

2x+2=3x+1
-x+2=1
-x=-1
x=1 lemonade
