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! :)
