PLEASE ANSWER ASAP!!!
Nolan purchased a shirt at store A. He paid $17.50 for the shirt. Scott purchased the same shirt at store B for $20.95. How much money did Nolan save by purchasing the shirt at store A instead of at store B? Please show your work and don’t forget the unit.

$20.95 - $17.50 = $3.45 simple math

The unit rate you mean? I’m confused,,
