Answer:
He worked 4 hours
Step-by-step explanation:
Clayton has already prepared 16 kilograms of dough and will continue preparing 1 kilogram of dough every hour
So, after n hours, the amount of dough he will have is:
A(n) = 16 + n
How many hours did clayton work if he prepared 20 kilograms of dough?
This is A(n) for which A(n) = 20. So
A(n) = 16 + n
16 + n = 20
n = 20 - 16
n = 4
He worked 4 hours
