The answer is 2/7 for this equation
First step cross multiplying.
6.2/2x+1=213/4
<span><span>(6.2)</span>*<span>(4)</span></span>=<span>213*<span>(<span><span>2x</span>+1</span><span>)
</span></span></span>
<span>24.8=<span><span>426x</span>+213</span></span><span>
Second Step flip with the equation.
</span><span><span>426x</span>+213</span>=<span>24.8
</span>
Third Step Subtract 213 from both sides.
<span><span><span>426x</span>+213</span>−213</span>=<span>24.8−<span>213
</span></span>
<span>426x</span>=<span>−<span>188.2
</span></span>
Fourth Step Divide both sides of 426.
426x/426 = -188.2/426
Answer is x= -0.441784
The number of different combinations of these items that you can make if you choose four (4) toppings is equal to 1.
<h3>How to calculate the combinations of these items.</h3>
In order to determine the combinations of these items that this person can make, we would use this mathematical model known as combination.
Mathematically, combination is calculated by using this mathematical equation:
<u>Where:</u>
- n is the total number of items.
- r is the number of times of choosing items.
<u>Given the following data:</u>
Let us assume you'll choose four (4) toppings.
Substituting the given parameters into the formula, we have;
⁴C₄ = 4/4
⁴C₄ = 1.

The cross-price elasticity of demand for hevs and gasoline is 2.57.
<h3>What is
cross-price elasticity of demand?</h3>
A cross-price elasticity of demand is an economic tool that measure the %change in quantity demand for a good after a change in the price of another
The demand is calculated by %change in the quantity demanded of one good over %change in the price of the other good.
Hence, the % of quanitty demanded is 36% and the % of change in the price is 14%
Cross-price elasticity of demand = 36% / 14%
Cross-price elasticity of demand = 2.57142857143
Cross-price elasticity of demand = 2.57
In conclusion, the cross-price elasticity of demand for hevs and gasoline is 2.57.
