Final answer:

To find the total amount of money they saved altogether, we set up a proportion to find out how much Greg saved. Greg saved $50, and Kevin saved $100. So, the total amount they saved altogether is $230.


Step-by-step explanation:

To find out how much money the three of them saved altogether, we need to determine the amount of money Kevin and Greg saved. Since Tanya saved $16 for every $10 Greg saved, we can set up a proportion to find out how much Greg saved. Let x represent the amount of money Greg saved:

10/16 = x/80

To cross multiply, multiply the numerator of one fraction by the denominator of the other fraction:

16x = 10 * 80

Simplifying the right side of the equation gives us:

16x = 800

Divide both sides of the equation by 16 to solve for x:

x = 800/16 = 50

Therefore, Greg saved $50. Since Kevin saved twice as much as Greg, Kevin saved $50 * 2 = $100.

Therefore, the total amount of money they saved altogether is $50 + $100 + $80 = $230.
