Answer:
The total amount customer pays for the discounted book is $ 30.21 .
Step-by-step explanation:
As given
A customer buys a different book that has an original selling price of $38.
The book is discounted 25%.
25% is written in the decimal form
= 0.25
Discount amount = 0.25 × Selling price of the books
= 0.25 × 38
= $ 9.5
Cost of the books after getting discount of 25% = Selling price of the books - Discount amount
= $ 38 - $ 9.5
= $ 28.5
As given
The customer must pay a 6% sales tax on the discounted price of the book.
6% is written in the decimal form
= 0.06
Sales tax amount = 0.06 × Cost of the books after getting discount of 25% .
= 0.06 × 28.5
= $ 1.71
Thus
Total amount pays by the customer for the books = Sales tax amount + Cost of the books after getting discount of 25%.
= $ 1.71 + $ 28.5
= $ 30.21
Therefore the total amount customer pays for the discounted book is $ 30.21 .

For this case we have the following inequality: y < 3x + 1 < br/ >
What we must do is to evaluate a point of the Cartesian plane and verify if it is in the shaded region.
The shaded region represents the solution of the system of equations.
For the point (0, 0) we have:
0 < 3(0) + 1 < br / >
0 < 0 + 1 < br / >
0 < 1 < br / >
Therefore, the point (0, 0) is in the shaded region because it satisfies the inequality.
Then, the points that are on the line, are not part of the solution because the sign is of less strict.

Answer:
Tomas added 6 to both sides of the equation instead of subtracting 6.
Step-by-step explanation:
Tomas is making trail mix using granola and walnuts. He can spend a total of $12 on the ingredients. He buys 3 pounds of granola that costs $2.00 per pound. The walnuts cost $6 per pound. He uses the equation 2x + 6y = 12 to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. He solves the equation for y, the number of pounds of walnuts he can buy.
Given:
2x + 6y = 12
where
x = number of pounds of granola y = number of pounds of walnuts
The correct solution to the problem
x = 3 pounds
2x + 6y = 12
2(3) + 6y = 12
6 + 6y = 12
Subtract 6 from both sides
6 + 6y - 6 = 12 - 6
6y = 6
Divide both sides by 6
y = 6/6
= 1
y = 1 pound
Tomas added 6 to both sides of the equation instead of subtracting 6.
