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

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

the answer will be the last one
