After the price was decreased by 15%, it became $2176. what would the price in each of the cases

The price was $2560.

Step-by-step explanation:

let x be the original price

x - 15% = 2176   (The price was decreased by 15% and became $2176)

Convert the percentage to decimal form by the percentage dividing by 100, which is the same thing as moving the decimal to the left by two places.

15% = 0.15

0.15x is the value that was shaved off of 2176.

1 - 0.15 = 0.85

Write a new equation and isolate x

0.85x = 2176

x = 2176/0.85   Divide both sides by 0.85

x = 2560

answer: the first graph

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
