There is a sales tax of $25 on an item that costs $310 before tax. the sales tax on a second item is $10 . how much does the second item cost before tax?

$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
