<h3 /><h3>What is the equation of variable?</h3>
The variable is the unknown part of the equation. Variable changes withe change in the quantities for any situation.
Properties of a equation-
- Equations are the expressions which consist of the variables, coefficients of variables and constants.
- The equations are used to represent the general problem in the mathematical way to solve them.
- The equation is used to show the relationship between the variables of the equation and the quantities in a situation.
Reuben rented a truck for one day. There was a base fee of $20.95, and there was an additional charge of 98 cents for each mile driven.
Reuben had to pay $302.21 when he returned the truck. Suppose the Reuben drive the truck for x miles. Thus,
Solve the equation to find the number of miles he drives,
Thus, the number of miles did Reuben drive the truck, with the base fee of $20.95, and an additional charge of 98 cents for each mile driven is 287 miles.

The question is incomplete, the complete question is;
A grocer has 18 kg of black tea worth $3.5 per kg. She wants to mix it with green tea worth $2.6 per kg to sell the mixture at $2.9 per kg. How much of green tea should she use?
Answer:
36
Step-by-step explanation:
Let the weight of the green tea used be x kg.
From the question:
We have:
18 kg of black tea at $ 3.5 per kg. Thus total cost of black tea is 18 x 3.5 = $ 63
Cost of green tea is $2.6 per kg. Total cost of green tea is 2.6 * x = $2.6x
Total weight of the mixture is 18 + x kg.
Total cost of the mixture is = $2.9 (18 + x)
Thus,
Total cost of black tea + total cost of green tea = Total cost of the mixture
$63 + $2.6 x = $2.9 (18 + x)
$63 + $2.6x = $52.2 + $2.9x
63 – 52.2 = 0.3 x
10.8 = 0.3 x
x = 10.8/0.3
x = 36
36 kg of green tea is needed
