Answer:
Yes the $20 bill will be enough to pay for all snacks.
Step-by-step explanation:
To slove this problem we have to find the cost of all snacks.
First lets find pretzels:
Each bag cost $3.49 and she bought 3 bags so
$3.49 * 3 = 10.47
Next find the hummus cost:
Each contaier is $4.19 and she bought 2 so
$4.19 * 2 = 8.38
Last add them together:
$10.47 + $8.38 = 18.85
That means we have more money left because $18.85 < $20.
