3. Carlos comprou uma camisa que custa R$ 18,50. Se ele pagou a camisa com uma nota de R$ 100,00, quanto lhe sobrou de troco?

R$ 80,75

R$ 80,15

4. Um caminhão transporta até 450 sacos de cimento . Se cada saco pesa 50 kg, quantos quilos de cimento, no máximo, esse caminhão pode transportar?

20 500 kg

21 500 kg

22 500 kg

23 500 kg

19 500 kg

The question asks how many kilograms of cement the truck can carry at maximum capacity. We are given that the truck can carry up to 450 bags of cement, and each bag weighs 50 kg. To find the total weight, we can multiply the number of bags by the weight per bag: 450 bags * 50 kg/bag = 22,500 kg. Therefore, the maximum weight of cement that the truck can carry is 22,500 kg.
