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%
