Hi!
So, we know the Mr. Collins already has 25 sections. So let's write an equation.
25 + 8s
(s = Saturday)
Now our value for s in this equation is 15. So put in the value..
25 + 8 · 15
25 + 120
145
The answer is 145
Hope this helps! :)
160% of 19 is 30.4
Convert 160 into a decimal: 160%/100 = 1.6
Multiply the decimal by 19: 1.6 × 19 = 30.4 <-- our answer.

0.9% of 54 is 0.486
Convert 0.9% in a decimal: 0.9%/100 = 0.009
Multiply the decimal by 54: 0.009 × 54 = 0.486 <-- our answer.
-------
15% of 376 is 56.4
Convert the percentage into a decimal: 15%/100 = 0.15
Multiply the decimal by 376: 0.15 × 376 = 56.4 <-- our answer.
8(4x+9)= 32x+72
Step-by-step explanation:
You distribute the 8 to the 4x and vet 32x and then you distribute the 8 to the 9 and get 72
