Answer: Gigi's pay $30, Bella's pay $25
Explanation:
You could use guess-and-check, or you could use a system fo linear equations
Gigi's pay is represented by the variable g and Bella's by a
g=b+5
g+b=55
Substitute the first equation into the second to get b+5+b=55, simplify to 2b+5=55. Subtract 5 from both sides, get 2b=50. Divide by 2 and find out Bella's pay is $25. Add 5 to that to get Gigi's pay of $30
