Answer:
x= 8 / 5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
20(x+2)+31=5(5x+10)+13
(20)(x)+(20)(2)+31=(5)(5x)+(5)(10)+13(Distribute)
20x+40+31=25x+50+13
(20x)+(40+31)=(25x)+(50+13)(Combine Like Terms)
20x+71=25x+63
20x+71=25x+63
Step 2: Subtract 25x from both sides.
20x+71−25x=25x+63−25x
−5x+71=63
Step 3: Subtract 71 from both sides.
−5x+71−71=63−71
−5x=−8
Step 4: Divide both sides by -5.
−5x / -5 = -8 / -5
x= 8 / 5
Answer:
Equation for the function: y=8x+20
Step-by-step explanation:
8 represents points per item/rate of change
20 represents the y intercept or what the person gains in the beginning that doesn't change.
8(16)+20
128+20
=148
After making 16 purchases the person will have 148 points.
