A music store gives every 20th customer A $5 gift card. Every 50th customer gets A $10 gift card. Which customer will be the first to receive both types of gift card?

Respuesta :

The 100th customer would be the first to receive both.
20×5=100
50×2=100
the 100th customer would be the first to receive both because 20x5=100 and 50x2=100
