Lollipops 7530

On Friday morning, we opened another box of lollipops, and by lunch, we sold a third of them at 4 crowns each. After lunch, we sold the rest of the box and raised the price to CZK 5 per piece. If there are 90 lollipops in the whole box, how much did we spend on it?

Correct answer:

x =  420 Kc

Step-by-step explanation:

n=90 x=4 3n+5 (n3n)=4 390+5 (90390)=420 Kc
