Answer:
To find the percentage decrease, we need to find the difference between the original price and the new price, divide that difference by the original price, and then multiply by 100 to express the result as a percentage.
The difference between the original price and the new price is:
990 - 765 = 225
Dividing the difference by the original price gives:
225 ÷ 990 ≈ 0.227
Multiplying by 100 gives:
0.227 x 100 ≈ 22.7
Therefore, the percentage decrease in the monthly price of the contract is approximately 22.7%.
