Answer provided by our tutors
let
r = the number of red candies tetel bought by the price of Php 13
y = the number of yellow candies tetel bought by the price of Php 22
the number of red candies she bought is thrice as much as the number of yellow candies
r = 3y
she paid a total of php 305 for the red and yellow candies
13r + 22y = 305
by solving the system of equations
r = 3y
13r + 22y = 305
we find
r = 15 red candies
y = 5 yellow candies
she bought 15 red and 5 yellow candies.
