-4
Step-by-step explanation:
haha we are learning this also!
to find the rate of change here is the formula
y2-y1 over x2-x1
familiar right?!
now just plug in the numbers
6-2=4
-3--2=-1
4/-1
-4
(20)(35) + (15)(15) - 125
This is right because the store bought 20 keyboards and sold each one for 35 dollars, and bought 15 phone chargers and sold each one for 15 dollars. so, 20 x 35 = 700 and 15 x 15 = 225. We use - 125 because we used that money to buy the products, so we need to subtract that out of the profit we are going to get. 700 - 225 = 925. Now we subtract the money we used, 925 - 125 = 800. The profit they gained was 800 dollars!
