n = d + 3

5n + 10d = 150 cents

Substitute to solve for "d":

5(d+3)+10d = 150

15d + 15 = 150

15d = 135

d = 9 dimes

n = d+3 = 9+3 = 12 nickels

So 12 nickels!!

An international company has 13,600 employees in one country. If this represents 19.3% of the company's employees, how many empl
user100 [1]
Hi there! To solve this question, we can write and solve a proportion. Let’s set it up like this: 13,600/x = 19.3/100. We do this, because we’re looking for the total amount of people, which would be the whole. We already have the part. Cross multiply the values in order to get 1,360,000 = 19.3x. Now, divide each side by 19.3 to isolate the variable. When you do, you get x is approx. 70,466.3212 or 70,466 when rounded to the nearest whole number. Plus, you can’t have a fraction of a person, anyway. The company has a total of 70,466 employees.
