Answer provided by our tutors
let
r = the number of regular fries orders
h = the number of healthier fries orders
the restaurant sold 1,214 orders of fries for a total of $2,043.06
r + h = 1214
h = 1214 - r
1.59r + 1.89h = 2043.06
plug h = 1214 - r into the last equation
1.59r + 1.89(1214 - r) = 2043.06
by solving we find
r = 838 regular fries orders
