Answer: 
Step-by-step explanation:
Let be "x" the price per pound for grapefruit, "y" the price per pound for oranges.
We know that Steve buys 2 pounds of grapefruit and 3 of oranges for $7.20.
This means that the sum of the products of
and
is $7.20. Then, we can write this equation to represent it:
Kennedy buys 4 pounds of grapefruit and 2 pounds of oranges for $8.80.
This means that the sum of the products of
and
is $8.80. Then, we can write this equation to represent this:
Therefore, we get that the system of equations that models the situation is:

......,.... the answer is h= -5
Don't really need an equation for this
0.15 is 15%
first 0.15 x 32 / 100 = 4.8
32 - 4.8 = 27.2 is the new price of the pan
Those lines stand for the absolute value, or how far away it is from zero.
If you draw a number line from -3 to 3, and plot the points x = 2 and x = -2, what similarities do you see?
Although one is two units to the right of 0 and one is two units to the left of 0, both x = 2 and x = -2 are two units away from zero. Therefore, the absolute value of both 2 and -2 is 2.
