Hey!
To solve this problem, we'll first start by creating an equation.
<em>Our Created Equation :
</em>
Now we'll solve it step by step to find the answer.
So we should begin by multiplying the to portion of our fraction.
<em>400 x 60 = 24,000</em>
Next, we divide our answer by 100, since that is the next step to our equation.
<em>24,000 ÷ 100 = 240</em>
So, our answer is...
<em>Paul has already saved</em> $240.00 <em>of the $400.00 he must pay for a new bike.</em>
Hope this helps!

Answer:
49
Step-by-step explanation:
Given:
Width = 0.4
Let's take the z value of 95% which is = 1.96
Let's assume population proportion p1 and p2 = 0.5
For margin of error E, the relation between the width and margin of error is 2E.
i.e 2E = 0.4
E = 0.2
To find the sample size, n, let's use the formula :
= 48.02
≈ 49
