Question

Carl lives in an apartment and pays the following expenses each month: electric bill, $34.60; TV streaming service, $24.99; and rent, $527.85. Estimate his total expenses for the month by first rounding each value to the nearest tens place.

a) $590

b) $550

c) $580

d) $588

Answer 1

c) $580. To estimate Carl's monthly expenses, round each cost to the nearest ten and sum them up: $30 for the electric bill, $20 for TV streaming, and $530 for rent, yielding an estimate of $580 for the total monthly expenses.

Step-by-step explanation:

To estimate Carl's total expenses for the month by rounding each cost to the nearest tens place, we would round his electric bill ($34.60), TV streaming service ($24.99), and rent ($527.85) using the following approach:

• Electric Bill: $34.60 rounds to $30 (nearest ten).
• TV Streaming Service: $24.99 rounds to $20 (nearest ten).
• Rent: $527.85 rounds to $530 (nearest ten).

Now, we add these rounded values together:

$30 (Electric Bill) + $20 (TV Service) + $530 (Rent) = $580

Therefore, the estimated total expenses for the month would be around $580, which corresponds to option c) $580.
