You would divide 377 by 2
which would be 188.5
12+20•3-3x-15
multiply the numbers : 20•3 = 60
12+60-3x-15
group like terms
-3x+12+60-15
add and subtract the numbers : 12+60-15=57
final answer = -3x+57
870 since 71 is closest to 70

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
