Find the cost per visit to the nearest cent: Health and Heart Club, $259 per year, 3 visits per week. a. $1.66 b. $7.19 c. $156
vagabundo [1.1K]

Answer:

a. $1.66

Step-by-step explanation:

We have been given that Health and Heart Club charges $259 per year. A person has 3 visits per week. We are asked to find the cost of per visit to Health and Heart Club.

We know that there are 52 weeks in one year. So total visits in one year would be 3 times 52 that 156 visits.

Now, we will divide total cost by 156 to find cost per visit.

\text{Cost per visit}=\frac{\$259}{156}

\text{Cost per visit}=\$1.660256

Rounding to nearest hundredths, we will get:

\text{Cost per visit}\approx \$1.66

Therefore, the cost per visit is $1.66 and option 'a' is the correct choice.
