Answer:
The total amount of money pays by Adrian is $14.5 .
Step-by-step explanation:
As given
Adrian purchases six tubes of paint and three paint brushes at a craft store.
Each tube of paint cost $2.50 each paint brush cost $0.50 .
Total cost of the 6 tubes of paints and 3 paint brushes = 6 × Cost of each tube of paint + 3 × Cost of each paint brush cost .
Putting the values in the above
Total cost of the 6 tubes of paints and 3 paint brushes = 6 × 2.50 + 0.50 × 3
= 15 + 1.5
= $16.5
As given
Adrian has a coupon for $2 of his purchase .
Total amount money pay by Adrian = Total cost of the 6 tubes of paints and 3 paint brushes - Coupon cost
Putting the values in the above
= $16.5 - $2
= $ 14.5
Therefore the total amount of money pays by Adrian is $14.5 .
Add the equations in order to solve for the first variable. PLug this value into the other equations in order to solve for the remaining variables.
The answer is:
(2, -3)
38 + 2n = 124
2n = 124 - 38
2n = 124 - 24 - 14
2n = 86
Therefore:
n = 43
