The equation that can be used to determine the tax rate, x is ;44.31 = 42 + (x% of 42) where x = 5.5%
<h3>How to write equation</h3>
- Cost of a shirt = $12.50
- Cost of each shorts = $14.75
- Cost of two shorts = 2 × $14.75
= $29.5
- Total cost = $12.50 + $29.5
= $42
- Total amount paid = $44.31
Total = total cost + x% of total cost
44.31 = 42 + (x% of 42)
44.31 = 42 + 42x/100
44.31 - 42 = 42x/100
2.31 = 42x / 100
x = 2.31 ÷ 42/100
= 2.31 × 100 /42
= 231/42
= 5.5%

The linear inequalities that will limit the solution region in a linear programming problem are called the origin.
<u>Explanation</u>:
- The x-axis is a horizontal line, and it is perpendicular to the y-axis. The origin is called the convergence of the two axes. This property allows multiplying a term or terms into a polynomial.
- The origin is a starting point, and in mathematics, the origin can also be said as the starting point.
- The co-ordinates for every other point are based on how far from the origin that point is. x and y are equal to zero at the origin and cross the x-axis and y-axis.
Answer:
There would be 2,120 dollars in that account
Answer: The equation is 5x = 12.50 and you will have the canoe for 2 and half hours or 2 hours 30 minutes.
Step-by-step explanation:
You rent the canoe for 5 dollars per hour and that can be represented by the expression 5x. After sometime you paid $12.50 meaning that to find the number of hours that you need the canoe, we need to set 5x to equal 12.50.
5x = 12.50 Solve for x by divide both sides by 5.
x = 2.5
This means you will need the canoe for 2 and half hours.
