Answer provided by our tutors
let
c = the cost of 1 chair
t = the cost of 1 table
table costs 3 times as much as one chair
t = 3c
after buying all the items she has $262 left
t + 5c = 2750 - 262
t + 5c = 2488
the total cost of all the items is $2,488
by solving the system of equations
t = 3c
t + 5c = 2488
we find
c = $311
