Answer:
96 bags of popcorn and 48 pretzels
Step-by-step explanation:
Let
x ----> the number of bags of popcorn sold
y ----> the number of pretzels sold
we know that
2.50x+2y=336 ----> equation A
x=2y ---> equation B
Solve the system by substitution
Substitute equation B in equation A and solve for y
2.50(2y)+2y=336
5y+2y=336
7y=336
y=48 pretzels
Find the value of x
x=2(48)=96 bags of popcorn
7 is a base, 4 is an exponent.
2/9 is the slope
Explanation:
8-4 = 4 over 10-1 = 9
The function (119x + 171) represents the amount, in dollars. Lionel will save 409 $ if he uses Quality Electric for a repair needing 2 hours of labor.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
The system of equations are;
p(x) = 68x + 81.
q(x) = 51x + 90.
So,
p(x) + q(x) = 68x + 81 + 51x + 90
p(x) + q(x) = 119x + 171
The function (119x + 171) represents the amount, in dollars, Lionel will save by having Quality Electric handle an x-hour repair instead of Phil’s Appliances.
p(x) + q(x) = 119x + 171
x= 2 hours
p(x) + q(x) = 119 (2) + 171
p(x) + q(x) = 409
Lionel will save 409 $ if he uses Quality Electric for a repair needing 2 hours of labor.
