• B. 5 chocolate and 9 strawberry cupcakes
  
• C. 9 chocolate and 5 strawberry cupcakes
  
• D. 7 chocolate and 7 strawberry cupcakes
  

Answer 1

The correct option is B 5 chocolate and 9 strawberry cupcakes


Say: Let's find out the number of cupcakes Fenix buys.

Steps:
$\bullet$ Each chocolate cupcake costs 10 coins = 1 Tens
$\bullet$ Each strawberry cupcake costs 1 coin = 1 Ones
$\bullet$ Fenix spends 59 coins.
$\bullet$ The number 59 is made up of 5 Tens and 9 Ones.
$\bullet$ So, to spend 5 Tens = 50 coins, Fenix has to buy 5 chocolate cupcakes.
$\bullet$ To spend 9 Ones = 9 coins, Fenix has to buy 9 strawberry cupcakes.
$\bullet$ Hence, Option C is the correct answer.
