30 cakes.

Step-by-step explanation:

Given:

A cake decorator can decorate 6 cakes in 90 minutes.

Question asked:

At this rate,how many cakes could he decorate during his 8-hour workday if he takes two -15 minutes coffee breaks?

Solution:

Total number of hours, he work = 8 hours

1 hour = 60 minutes

8 hours = 60 $\times$ 8 = 480 minutes

Coffee break = 2 of 15 minutes, 15 + 15 = 30 minutes

Remaining working hour = 480 - 30 = 450 minutes

In 90 minutes, he decorate number of cakes = 6

In 1 minute, he decorates number of cakes = $\frac{6}{90}$

In 450 minutes, he decorates number of cakes = $\frac{6}{90}\times450=\frac{2700}{90} =30\ cakes$

Therefore, at this rate, he can decorate 30 cakes.
