Fiction books : 20 % ( 5 books )
20 % = 5
1 % = 5 / 20 = 0.25
100 % ( whole collection ) = 0.25 x 100 = 25

Hence, Lisa has 25 books in all.

Hope this helps you! If you don't understand any steps you can ask me :)

Omar wants to purchase a bike helmet for 22.55 and a bike for 134.45.

noname [10]

Answer:

$169.96 dollars

Step-by-step explanation:

Given the following questions:

8.25% of 22.55 and 134.45

In order to find the answer, we will have to add the initial costs of the items together, then we will calculate using the formula for percentages to find the tax rate.

$22.55+134.45=157$
$157$

<u>Calculate the percentage:
</u> $\frac{p\times c}{100}$
$\frac{8.25\times157}{100} =8.25\times157=1295.25\div100=12.9525$
$=12.9525$
$12.9525$
$2 < 5$
$=12.96$

<u>Add the sales tax:</u>
$157+12.96=169.96$
$=169.96$

Which means the two items along with an 8.25% sales tax costs "$169.96 dollars."

Hope this helps.
