Question

Doreen has $20. She wants to buy a pair of earrings that costs $7.58 and a necklace that costs &13.36. Does Doreen have enough money? Explain your reasoning

Answer 1

Hi!

To solve this, we need to know how much the earrings and necklace cost together, then we need to know if it's more or less than how much she has ($20)

So first, add the costs together.

     7 . 5 8
+ 1 3 . 3 6
---------------
   2 0 . 9 4

The necklace and earrings cost $20.94 which is more than $20. 

The answer is no, Doreen does not have enough money.

Hope this helps! :)
