I hope I am reading the problem right: The price of a mountain bike increased by 20% in the past year. The value is $150. What was the value of the mountain bike last year?
Let's simplify this. One year, there was this radical mountain bike that used to have an unsaid price, <em>x. </em>That year, that price of x increased by 20% more than it was before, or <em>120% times the original value</em>. Because of that, it's now $150.
We can equation this.
1.20x = 150
x = 150/1.2
x = 125
The bike, I believe, cost $125 last year. Hope this helps!
Answer:
C)two thirds x + 10 = 21
Step-by-step explanation:
The equation for determining how much it would be paid for the student tickets is shown below:
Given that
The ticket of an adult is $21
Now let us assume the price of the student ticket be x
So two third would be 2 ÷ 3x
And for adult it would be
2 ÷ 3x + 10
Now the equation is
2 ÷ 3x + 10 = 21
So after solving this the option c is correct
And the rest of the options are wrong
