Answer:
It is decreased by 76 percent.
Step-by-step explanation:
The key skills are percentage and multiplication with percentages.
- You first have to get a variable. Let's use the letter o as a variable (o For orginial cost).
- Then we have to find out how much it is when o is decreased by 40 percent. 100% (or the whole) - 40% is 60%. Therefore, with a 40 percent decrease, It would be 60% of o, or 0.6o.
- Then, if it decreases by 60 percent, the final number would be 100% - 60 % or 40% of 0.6o. This means itbwould be 0.4 × 0.6o which is 0.24o
- 0.24o means that o is 24 percent of its orginial number, which is 100% - 24% or a 76 percent decrease.

Answer:
Rounding x = 5.52
Step-by-step explanation:
2.1x - 3.6 = 8
Add 3.6 to each side
2.1x - 3.6+3.6 = 8+3.6
2.1x = 11.6
Divide each side by 2.1
2.1x/2.1 = 11.6/2.1
x =5.523809524
Rounding x = 5.52
