Answer:
The amount of money that Alex has is $47.4
Step-by-step explanation:
Let
x----> amount of money that Alex has
y----> amount of money that Jennifer has
z----> amount of money that Jennifer Shannon has
we know that
x+y+z=91 ----> equation A
x=3y -----> equation B
y=z-12 -----> z=y+12 -----> equation C
substitute equation B and equation C in equation A and solve for y
(3y)+y+(y+12)=91
5y=91-12
y=79/5
y=$15.8
Find the value of x
x=3y ----> x=3(15.8)=$47.4
