Answer:
55-4x=22
Step-by-step explanation:
We want to know how long it'll take until 22 mints are left, so we already have the "=22" part.
Customers are taking 4 mints per hour, so the number is subtracting. So now we have "-4=22".
The 4 is being taken from the 55 mints per hour, so 4 is multiplied by "x", so now the equation is "-4x=22".
The final equation would be
55-4x=22.
