Question

wich is a better deal, 5 tickets for $12.50 or 8 tickets for $20.16

Answer 1

5 tickets for $ 12.50

Explanation

to figure out this we need to find the unit rate

so

Step 1

the rate is given by:

$\text{rate}=\frac{Numbe\text{r of tickets}}{\cos t\text{ of those tickets}}$

then

a) for 5 tickets and $12.50

replace and calculate

$\begin{gathered} \text{rate}=\frac{Numbe\text{r of tickets}}{\cos t\text{ of those tickets}} \\ \text{rate}=\frac{5\text{ tickets}}{12.5\text{ \ }}=0.4\text{ tickets per dollar} \end{gathered}$

b) for 8 tickets and $20.16

replace and calculate

$\begin{gathered} \text{rate}=\frac{Numbe\text{r of tickets}}{\cos t\text{ of those tickets}} \\ \text{rate}=\frac{8\text{ tickets}}{20.16\text{ \ }}=0.396\text{ tickets per dollar} \end{gathered}$

therefore, the better deal is 5 tickets for $ 12.50, you will get more tickets per dollar

I hope this helps you
