Answer:
80 sets costing $25/set
120 sets costing $45/set
Step-by-step explanation:
let x = number of sets costing $25/set
let y = number of sets costing $45/set
we have to build eqautions form the info given
(1) . total sets = 200 x + y =200
(2) . total sets = 7400 25x + 45y = 7400
use the substitution method

2: both take an amount of space
3: cubic inch
Hope this Helps!
Y=1/4x -2
since the slope is already given , i put that as the m , then i found the y intercept by plugging the coordinates points in the equation , but the y intercept is also already given in the point (0,-2) . it already shows that when x is 0 y is -2. hope this helps
It should equal to 180 so 180-157=23
