we are given
slope is
y-intercept is (0,-3)
now, we can use slope intercept form of equation
where
m is slope
b is y-intercept
now, we can plug these values
we get
now, we have to write it in
Ax+By =C form
so, we will multiply both sides of equation by 3
Subtract both sides by 2x
so,
Answer is
We define the variables of the problem:
x = expensive tea
y = less expensive tea
We write the system of equations:
7x + 4y = 6.10 * (140) = 854
x + y = 140
The system of equations is:
7x + 4y = 854
x + y = 140
Resolving we have:
x = 98
y = 42
Note: see attached image for the solution.
