Answer: No, as the total cost of the 3 shirts w/ sales tax is $45.36 and she only has $45.
Step-by-step explanation:
Start by finding the price of one shirt on sale.
This equals 3.6 which is how much will be deducted from the original price.
One shirt costs when its 20% off.
This is equal to $14.40.
Since she wants to buy 3 of them we just multiply the $14.40 by 3.
This equals $43.2 but this is without a 5% sales tax which is normally added to the total end price.
To add a sales tax you take the sales tax percent plus 1 and multiply it to the $43.2.
This means the total price of Kayla's purchase will be $45.36.
This is over her $45 she has so she can not buy it.
The volume of a pyramid is given by:
Where:
• Ab is the area of the base,
,• h is the height.
In this case, we have:
• a = 3 units,
,• b = 7 units,
,• c = 9 units,
,• Ab = b * c,
,• h = a = 3 units.
Replacing the data in the formula above, we get:
Answer: 63 units³
