Question

Elsa, Alan, and Deon have a total of $82 in their wallets. Alan has 3 times what Deon has. Deon has $7 less than Elsa. How much do they have in their wallets?

Answer 1

Alan=$45

Deon=$15

Elsa=$22

Explanation:

Let

Elsa=x

Deon=x-7

Alan=3(x-7)

Total=$82

x+(x-7)+3(x-7)=82

x+x-7+3x-21=82

5x-28=82

5x=82+28

5x=110

x=110/5

=22

Elsa=x=$22

Deon=x-7

=22-7

=$15

Alan=3(x-7)

=3(22-7)

=3(15)

=$45
