The students in Alexis’ class sold t-shirts for a fund raiser this year and last year. This year, the selling price of each t-shirt was $12.50

The price this year represents 6% more than the selling price of each t- shirt last year.
What was the selling price of each –t-shirt last year?

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
