Last year, the price of a certain computer was $150 more than it is now. this year's price is 3/4 of last year's price. how much does the computer cost this year?

The computer's price for this year = $450

Step-by-step explanation:

Let,

The computer's price for this year = X

The computer's price for last year = X + 150

According to the question,

X - X*(3/4) = 150*(3/4)

or, X - 3X/4 = 450/4

or, (4X - 3X)/4 = 450/4

or, X/4 = 450/4

or X = 450

Therefore, The computer's price for this year, X = $450

So, it will be less than $150 from last year.

i'm sure goog can you get that answer

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
