Answer: We need how much he spent on the whole thing
Step-by-step explanation:
It isn't really specific because he could of bought 6 pencils and 9 markers for all we know so we need the total how much he spent on all 15 markers and pencils
Answer:
-18x^2 -54x + 72
Step-by-step explanation:
The answer to this equation is A) 50 times larger
2x + y = 350
x + 2y = 475
3x + 3y = 825
x + y = 275
x = 275 - y
(plug back into first equation)
2(275 - y) + y = 350
550 - 2y + y = 350
550 - y = 350
-y =-200 or y = $200 (dog)
therefore, x = $75 (cats)
Check
2(75) + 200 = 350
75 + 400 = 475
HAPPINESS! :)
