Answer:
Jesicaa=$59
Ashley=$71
Devyn=$98
Step-by-step explanation:
Let Jessica's earning be x:
[tex]Jessica=x\\\\Ashley=x+12\\\\Devyn=2x-20[/tex]
-Given that the total earnings for the three was$228. earnings per person is calculated as:
#Equate their earnings to the 228 to solve for x:
[tex]x+(x+12)+(2x-20)=228\\\\4x-8=228\\\\4x=236\\\\x=59[/tex]
#Substitute for x in each earning equation to determine individual earnings:
[tex]Jessica=x=59\\\\Ashley=x+12=59+12=71\\\\Devyn=2x-20=59\times 2-20=98[/tex]
