Answer:
The answer is 0.45 or if you want to put as a fraction 9/20
Step-by-step explanation:
You can use this equation to figure out for any number of seconds how many items the cashier can ring up.
For instance if you wanted to know if 100 seconds how many items could be rung up:
y = .45x
y = .45(100) This would be 45 items.
If you wanted to know how many items could be rung up in 10 seconds:
y = .45(10) This would be 4.5 items.
You could use this equation for any amount of time to figure out how many items could be rung up.
