Question

Clayton has already prepared 16 kilograms of dough and will continue preparing 1 kilogram of dough every hour how many hours did clayton work if he prepared 20 kilograms of dough

Answer 1

He worked 4 hours

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
