12 milkshakes

Explanation:

We can solve this problem using algebra to write and solve an equation.

Define the variable first:

Let the number of milkshakes be x.

income from milkshakes:
He makes $12 for each of x milkshakes = 12 xx x = 12x

He is paid $200 per month for working,

Total income = 12x+200 = 344

12x = 344-200 = 144

12x = 144

x = 12
