not sure if there is tax or not, but there are two ways you could do this.

#1

$48 x 0.25 = how much discount.

$48 - how much discount = total

#2

$48 x 0.75 (100%-25%) = total.

Either way, you should get the same answer...

you can find the answer by introducing a variable to help find the percent you are trying to find (people who oonly bring an umbrella) also draw a venn diagram and see if it helps.

I also believe that there was already a post like this several years ago...

make sure that you dont mix up the students that bring both...

(if you would like to check your answer, I got 64%)

so like theres 5 vowels, and then the other 2 letters can be from the 26 letters of the alphabet... right?

I'm not sure if I'm correct because im not very good at math. But:

12 (1+2 = 3), 21 (2+1 = 3), 111 (1+1+1)... 3

not sure lmao
