Question
A transport company charges $10 for the deal and 25 cents for every one kg of apples. The total transport company charged David is $100. The total weight he transported is
- 400 kg
- 300 kg
- 360 kg
- 340 kg
Hint:
An equation has a constant, variable and an equal to sign. It has two sides LHS and RHS. A linear equation in one variable is equation with only one variable and in which the highest degree is 1. Here, we have to find the value of unknown value, by operating both sides with the same number so that the equation will be balanced.
The correct answer is: 360 kg
In the question it is given that, the charge for deal is $10.
Charge of 1kg of apples= 25 cents= $0.25
Total amount paid by David= $100
We have to find the total weight he transported.
Step 1: Convert the word problem into numerical equation.
Let the weight he transported be x kg.
So, equation will be
Amount paid by David= Charge for one deal+ Charge for per kg
Total weight he transported
100= 10+0.25x
Bring all the terms containing variables in one side by operating same numbers on both sides to balance the equation.
Step 2: Subtract both sides by 10.
100-10= 10+0.25x-10
100-10= 0.25x
90= 0.25x
Step 3: Divide both the sides by 0.25.
So, the total weight transported by David is 360 kg.
Therefore, the correct option is c, i.e., 360kg.
