Answer:
They won [tex]\£63[/tex] in total
Step-by-step explanation:
Let
x ----> Mark's money
y ----> Henry's money
we know that
[tex]x=27[/tex] ----> equation A
[tex]\frac{x}{y}=\frac{3}{4}[/tex] ----> equation B
substitute equation A in equation B
[tex]\frac{27}{y}=\frac{3}{4}[/tex]
solve for y
[tex]y=27(4)/3\\y=36[/tex]
we have that
[tex]x+y=27+36=\£63[/tex]
