Find the cost of 1 inch by dividing 80 cents by 16 inches, then multiply that cost by 11:
0.80 / 16 = 0.05 per inch.
11 inches x 0.05 = 0.55
It will cost 55 cents.
Because it's decreasing, you use the formula (1-x/100)y with x the percentage decreased which is here 40, and y the number decreased which is here 90
So we get
(1-40/100) * 90
(100/100 - 40/100) * 90
60/100 * 90
5400/100
54
So 90 decreased by 40% is 54

75% of something is 3/4 as 75/100 is simplified to 3/4. So 3/4 of 200 is 200÷4=50×3= C) 150
