Problema Solution
Salma, Tom, and Felipe served a total of
145
orders Monday at the school cafeteria. Tom served
7
more orders than Salma. Felipe served
4
times as many orders as Salma. How many orders did they each serve?
Answer provided by our tutors
let
s = the number of orders that Salma served
t = the number of orders that Tom served
f = the number of orders that Felipe served
Salma, Tom, and Felipe served a total of 145 orders Monday at the school cafeteria:
s + t + f = 145
Tom served 7 more orders than Salma:
t = 7 + s
Felipe served 4 times as many orders as Salma:
f = 4s
by solving the system of equations:
s + t + f = 145
t = 7 + s
f = 4s
we find
s = 23 orders
t = 30 orders
f = 92 orders
