I am assuming the problem is asking you to find an equation repersenting the situation.
In this case, realize that 150 will be a constant, and 60 will be attached to the 
variable, since the price of the textbooks changes based on how many textbooks there are.
Thus, the equation is:
Our answer is 60x + 150 = y.
Real answer
48
*26
------
1,248
Estimate
50
*25
------
1,250
So the answer is..
Estimating is helpful because it makes sure you answered correctly. No, this answer is incorrect and if he had done the estimate he could have seen how he was wrong.
Answer:
Rs. 42500
Step-by-step explanation:
100% + 25% = 125% ÷100 = 1.25
34000 x 1.25 = 42500
<span>Starting with x−24/x<10 multiply everything by x.
x^2-24<10x
Subtract 10x from both sides.
x^2-10x-24 < 0
Factor.
(x-12)(x+2) < 0
(x+2) is always positive since x > 0, but (x-12) is negative when x is a value between 0 and 12. This negative value for (x-12) satisfies that the left side is less than 0. Thus the solution set for x is (0,12).</span>
Answer:
5 cups of sugar
Step-by-step explanation:
To make 60 cookies you need 3 cups of sugar.
If you divide 60 / 3 you get 20.
That means: 1 cup = 20 cookies
Therefore to make 100 cookies you need 5 cups of sugar!
