Oranges
2(3.50) = 7.00
apples
4(3.25) = 13.00
carrots
2(1.90) = 3.80
potatoes
1(1.20) = 1.20
7 + 13 + 3.80 + 1.20 = 25.00 * .05 = 1.25
$25.00 - 1.25 = $23.75

Answer:
(-7, 5)
Step-by-step explanation:
Since both of them are equal to y, you could just set them equal to each other.
5/7x + 4 = -1/7x - 2
6/7x = -6
x = -7
Now just plug x back to one of the equations:
y = -1/7*(-7) - 2 = 7 - 2 = 5
Therefore, the solution to the system is (-7, 5)
30-39 is the interval because it has the most responses
