Rina is planning a surprise party for her friend. She needs to buy decorations, food, and drinks. She has a budget of $120. She spends 1/3 of her budget on decorations, 1/4 on food, and the rest on drinks. However, she also has a coupon for 20% off on decorations. How much does she spend on drinks?

Jawaban: $50

Without coupon, decorations would be $40, but with 20% off, she spends $32. Food is $30. Total spent on decorations and food is $62. Drinks cost $120 - $62 = $58? Wait, that's not an option. Let me recalculate: Budget $120. Decorations: 1/3 of $120 = $40, with 20% off = $32. Food: 1/4 of $120 = $30. Total so far = $62. Drinks = $120 - $62 = $58. But $58 is not an option. Hmm, perhaps I made a mistake. The options are 50,60,55,45. Maybe the coupon applies to the total? Or maybe the fractions are of the remaining? Let's check: If she spends 1/3 on decorations and 1/4 on food, that's 7/12, leavin
