Question

I am stuck on this question and i really need help

Answer 1

Waz, start by giving a symbol to the quantity desired.

Lets call the number of questions “q”.

Now, how many did Jesse get correct? .8 * q

but we also know a number for that— 100.

so you have an equation

100 = .8 * q

solve this for q, and you’ll have your answer.

Hint: divide both sides by .8
