Brut [27]
We can write a proportion for this question
5 out of 32 students and we have to find how many (x) out of 800
5/32 = x /800
cross multiply
5*800 = 32x
4000 = 32x
divide both sides by 32
125 = x

About 125 students of the 800 ride their bikes to school.

Hope this helps :)

A store bought a tent for $230 and marked it up 65% The store sells the tent with the 8% tax what is the total cost of the tent
salantis [7]

Answer:

$409.86

Step-by-step explanation:

To find the price after marking it up, 230 x 0.65 = 149.5

230 + 149.5 = 379.5

Usually we add tax after the discount/markup.

379.5 x 0.08 = 30.36

379.5 + 30.36 = $409.86

Hope this helps!
