Answer: the system of equations are
0.1x + 0.04y = 162
y = 2x
Step-by-step explanation:
Let x represent the total dollar amount of the phone sales she makes.
Let y represent the total dollar amount of the computer sales she makes.
Charlotte earns a 10% commission on the total dollar amount of all phone sales she makes, and earns a 4% commission on all computer sales. If she earned a total of $162 in commission, it means that
0.1x + 0.04y = 162
Charlotte had twice as much in computer sales as she had in phone sales. This means that
y = 2x
11.5 x 3.2 = 36.8m
-36.8 meters change in elevation
