Answer 1

Hint: In the question we are asked if Apples on sale for $\$ 1.20$ a pound and if Lonnie bought $\dfrac{3}{4}$ of a pound, how much money did he spend on apples. To do this question, first we have to take the money spent on the apples as x as it is an unknown variable. Next we should write the equation as $x=1.2\times \dfrac{3}{4}$. After solving this equation, we get the value of x. This x is the money spent on the apples.

Complete step by step solution:
In the question we are asked if Apples were on sale for $\$ 1.20$ a pound and if Lonnie bought $\dfrac{3}{4}$ of a pound, how much money did he spend on apples.
In order to do this question, first we have to take the money spent on the apples as x as it is an unknown variable. Next we should write the equation as $x=1.2\times \dfrac{3}{4}$. This x is the money spent on the apples.
First, take the money spent in apples as x and write the equation.
$\Rightarrow x=1.2\times \dfrac{3}{4}$
Next, we have to simplify the equation. Therefore, we get:
$\Rightarrow x=1.3\times 3$
$\Rightarrow x=0.9$
Finally, we get the x as 0.9. So, the money spent on apples is $\$ 0.9$.
Therefore, we get the final answer of the question as $\$ 0.9$.

Note:
This question can be done by first writing the question as an equation. Substitutions and the calculations should be done correctly. Otherwise, you may get the wrong answer. And do not forget to write the units at the end. Units are very important.
