This isn’t 30 points this is 15
Answer:
a. $17.50
b. $11.25
c. $5
Step-by-step explanation:
First, set up an equation:
20 - 1.25x = m
Now let's substitute in for x (which is how many snacks you buy) to solve for m (the amount of money you have left):
20 - 1.25 ( 2 ) = m
20 - 2.50 = m
17.50 = m
20 - 1.25 ( 7 ) = m
20 - 8.75 = m
11.25 = m
20 - 1.25 ( 12 ) = m
20 - 15 = m
5 = m
Step-by-step explanation:
A Tyler made mistake in the third step
B Tyler didi not multiply 4 by 6
C 9 - 20x + 24
- 20x + 15
-5 (4x - 3)
You wanna simplify the expression first
5(3m+2p+m)
=15m+10p+5m
so B would be correct
