Answer:
$124
Step-by-step explanation:
If the tax value of a item that costs $310 before tax is $25, we can calculate the tax percentage by dividing the tax costs by the item value without taxes:
tax = 25/310 = 0.0806
So, for the second item, if the tax costs were $10, we can calculate the item value (this value will be called X) with the following equation:
tax = 10/X = 0.0806 -> X = 10/0.0806 = $124
Another way of solving this problem, is by rule of three:
tax of 25 for an item of $310,
tax of 10 for an item of $X
25/10 = 310/X -> X = 310*10/25 = $124
