Final answer:
The exact cost for five theater tickets at $6.50 each is $32.50. Rounding to the nearest whole number and estimating would yield $35, which is closer than the $50 estimate but still higher than the exact cost.
Step-by-step explanation:
The question asks whether $50 is a reasonable estimate for the cost of five theater tickets, each priced at $6.50. To solve this, we need to multiply the number of tickets by the cost per ticket. Performing this calculation: 5 tickets x $6.50 = $32.50. Hence, the exact cost for five tickets is $32.50.
Now to address the aspect of rounding to a reasonable estimate, if we round $6.50 to the nearest whole number, we get $7. So, estimating with the rounded figure: 5 tickets x $7 = $35. While the estimate of $50 is higher than the exact cost, it is not an unreasonable estimate, though it is not as close as the $35 estimate using rounded numbers. It's advisable to estimate considering the exact or rounded cost for better precision.
