j4 + m3 = p
If you multiply j, which is the number of jumbo popcorns sold by its price, you are given the profit of the Jumbo boxes for a single day. If you multiply m, which is the number of mini popcorns sold by its price, you are given the profit of the Mini boxes for a single day. If you add the profits from both boxes together... you are given p, which is the total profit for the day.
Answer:
g (
x
−
7
)
= x 3 − 21 x 2 + 147
x − 343
Step-by-step explanation:
Make it 2x-y=7, 2x+y=5, now do elimination. -2y=2, y=-1.
Plug in -1 for y and solve for x
2x+1=7, x=3
Final answer: x=3, y=-1
