This problem is essentially testing those how to read and how to pay attention to detail. The best way to approach this is to make a list.
If we break it down slowly, We see that we have 2 $10. This means $20. 4 $1 bills is equal to $4. 3 quarters is equal to $0.75. 5 dimes is equal to $0.50, and 8 pennies is equal to $0.08. If we make a list, we can easily add them together as so:
20+4+.75+.5+.08.
The total amount of money Zoe has is: $25.33
