Answer:
see the explanation
Step-by-step explanation:
The correct question in the attached figure
Let
q ----> the number of quarter coins in the piggy
d ----> the number of dollar bills in the piggy
we have
[tex]5q=d[/tex] ----> equation A
[tex]8q+d=91[/tex] ----> equation B
Solve the system by substitution
substitute the value of d of equation A in equation B
[tex]8q+(5q)=91[/tex]
solve for q
combine like terms
[tex]13q=91[/tex]
divide by 13 both sides
[tex]q=7[/tex]
Find the value of d
[tex]d=5(7)=35[/tex]
therefore
The number of quarter coins in the piggy is 7 and the number of dollar bills in the piggy is 35
The total value in the piggy is
[tex]\$0.25(7)+\$35=\$36.75[/tex]
