Answer:
11m + 3
Step-by-step explanation:
First you have to find the product of Mai's age and 11. You can do this by adding 11 as the coefficient to the variable m like 11m. Then you have to add 3 to that product, which you can do by adding 3 to it like 11m + 3. In the end, you have an expression that first multiplies Mai's age by 11 and then adds 3.
