My question is: Betty is planning to host her friends over for a party. She buys drinks, cakes, and ice creams at a unit cost of $2, $10, and $5 respectively. How much does she spend if she buys 10 drinks, 5 cakes, and 100 ice creams? Your thoughts:
User
The amount she spends on buying drinks is $2 * 10 = $20. The amount she spends on buying cakes is $10 * 5 = $50. The amount she spends on buying ice creams is $5 * 100 = $500. The total amount she spends is $20 + $50 + $500 = $570. The final answer: 570.
