Egg rolls are the best

Excellent things

I love eggrolls, hoverboards, and xbox ones are my favorite things.I gave the cashier $124.30. The cashier gave me back $30.10. How much did these things cost.

Explanation

First, I drew the number line

Next, I split the second number into ones and tenths

Then, you show your jumps from one number to another

Finally, I got the answer of $124.30-30.10=$94.20
