We call x the 4 points-worth problems and y the 3 points-worth problems
You know that x+y = 32
4x+3y = 111
You know that the difference from the x and y is 32 so write:
x = 32-y
Substitute at x the value of 32-y
4(32-y)+3y = 111
128-4y +3y = 111
-4y+3y = 111-128
-y = -17
y = 17
The answer is “a”.

the dot is open and the arrow is pointed to the left.
Add 7 to each side of the inequality.
w < 28.
105 times 15= 1575

1140+1575= 2715
(2715)(d)= x
x being the total amount the company paid
