Answer provided by our tutors
let
'a' represent the sales in restaurant A
'b' represent the sales in restaurant B
the total sales at restaurant A were $400,000 more than at restaurant B:
a = 400,000 + b
Total sales at the two stores were $550,000.000:
a + b = 550,000
by solving the system of equations:
a = 400000 + b
a + b = 550000
we find
a = $475,000
b = $75,000
