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

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! :)
