To calculate Pedro's total expenses and change, you need to add up the costs of sugar, coffee, and rice, and then subtract that total from the R$100.00 bill. Here's how you can do it step by step:
Calculate the cost of sugar:
Cost of sugar = 9 kg * R$1.80/kg = R$16.20
Calculate the cost of coffee:
Cost of coffee = 6 packets * R$3.90/packet = R$23.40
Calculate the cost of rice:
Cost of rice = 8 kg * R$2.70/kg = R$21.60
Add up the costs of sugar, coffee, and rice:
Total cost = R$16.20 + R$23.40 + R$21.60 = R$61.20
Now, subtract the total cost from the R$100.00 bill to find the change:
Change = R$100.00 - R$61.20 = R$38.80
Pedro received R$38.80 in change after paying for his purchases with a R$100.00 bill.
