question 15 of 25
seven friends go to the movies. the price for each ticket is $8.99. one person thinks the total for all seven people will be around $63.
is this a reasonable estimate? why?
a. no, a reasonable estimate is around 5·$9 = $45.
b. yes, a reasonable estimate is around 7·$9 = $63.
c. yes, a reasonable estimate is around 8·$10 = $80.
d. no, a reasonable estimate is around 10·$10 = $100.

Explanation:

Step1: Round ticket price up

$\$8.99 \approx \$9$

Step2: Calculate estimated total

$7 \times \$9 = \$63$

Step3: Verify estimate reasonability

The actual total is $7 \times \$8.99 = \$62.93$, which is very close to $\$63$, so the estimate is reasonable.

Answer:

B. Yes, a reasonable estimate is around $7 \cdot \$9 = \$63$.
