Answer 2

Given: Total worth of avocados = Php 900

           Price of ripe avocados = Php 55

           Price of unripe avocados = Php 45

           Number of unripe avocados purchased = 9

To Find: Number of ripe avocados purchased.

Solution:

Let the number of ripe avocadoes be $x$.

Total worth = (Price of 1 ripe avocado × Number of ripe avocados bought) + (Price of 1 unripe avocado × Number of unripe avocados bought)

∴ 900 = (55 × $x$ ) + (45 × 9)

⇒ 900 = 55$x$ + 405

⇒ 55$x$ = 900 - 405

⇒ 55$x$ = 495

⇒ $x$ = 9

∴ The number of ripe avocados bought is 9.

Answer: Option B. 9 is the correct answer.

9 ripe avocados were bought.
