Final answer:
The shopper has $1.93 left.
Step-by-step explanation:
The student spent $75.64 at one store and $22.43 at the next store. To find out how much money the shopper has left, we need to subtract the total amount spent from the initial amount of money.
Initial amount of money: $100.00
Amount spent: $75.64 + $22.43 = $98.07
Money left: $100.00 - $98.07 = $1.93
Therefore, the shopper has $1.93 left.
