Problema Solution
Sean bought 8 lemons and 4 limes for $8.00. At the same prices, Kim bought 3 lemons and 9 limes for $8.25. Find the price per lemon and the price per lime.
Answer provided by our tutors
let price of lemons be x and lime be y.
8x+4y = 8 => 2x+y = 2
3x+9y = 8.25
3x + 9(2x-2) = 8.25
21x = 26.25
x = 1.25
y = 0.5
