The United States government used to make coins of many different values
Papessa [141]

Answer:

1. 50%

2. 3%

3. 20%

4. 200%

Step-by-step explanation:

Here, we want to find the worth of each coin as a percentage of $1

We simply divide the worth by $1 and multiply by 100%

$1 is same as 100 cents

Thus;

1. 50 cent

= 50/100 * 100% = 50%

2. 3 cents

= 3/100 * 100% = 3%

3. 20 cents

= 20/100 * 100% = 20%

4. $2

= 2/1 * 100% = 200%

<em>Now for 1 U.S dollar, we need to plug D=1 into the above equation. So, we will get......... </em>

<em> E=17/20(1)</em>

<em>E=1/20=0.85</em>

<em>0.85 Euros have the same amount as 1 U.S dollar. </em>
