A cup of milk contains 170 kcal.

Explanation:

13 color(red)(cancel(color(black)("g carbohydrate"))) × "4 kcal"/(1 color(red)(cancel(color(black)("g carbohydrate")))) = "52 kcal"

9.0 color(red)(cancel(color(black)("g fat"))) × "9 kcal"/(1 color(red)(cancel(color(black)("g fat")))) = "81 kcal"

9.0 color(red)(cancel(color(black)("g protein"))) × "4 kcal"/(1 color(red)(cancel(color(black)("g protein ")))) = "36 kcal"

"Total kilocalories = (52 + 81 + 36) kcal = 170 kcal"
