Question

Sumatra sells avocados, cauliflower, and pineapples to pay his rent. He sells avocados at $4 apiece, cauliflower at $2 apiece, and pineapples at $10 apiece. He sells 1 pineapple for every 5 avocados plus 3 times the number of cauliflower he sells.

Sumatra's rent is $800. What is the least number of cauliflower he must sell if he sold 35 apples?

Answer 1

35 pineapples at $10 a pineapple gives him $350

5 avocados at $4 an avocado gives him $20

350+ 20= 370 rent is 800. he needs another $430 just to pay the rent

califlower is $2 a piece. He needs to sell 430/2 = 215 califlowers
