Jasmine has only $46.50 to spend at forever 21. She wants to buy a shirt that costs $19, including tax, and some bracelets that

ivanzaharov [21]

46.50 - 19 = 5.50x

We get the 46.50 from her budget and the 19 from the shirt she wants to buy. If we subtract 19 from 46.50, we'll get the amount of money Jasmine can spend on bracelets.

46.50 - 19 = 27.50

She has $27.50 to spend on bracelets. Now, we divide that by 5.50 (the price of a bracelet) to see how many she can buy.

27.50 ÷ 5.50 = 5

Jasmine can buy 5 bracelets.

Hope this helps!

if a dealer buys a car from a manufacturer for $20,480 and sells it for $26,808...what is his markup? rounded to the nearest ten

yulyashka [42]

To find the markup, substract the price at which the car was bought from the price at which the car was sold:

$26,808-20,480=6328$

To find the markup as a percentage from the original price, set 20,480 to be equal to 100%. If <em>x%</em> represents 6328, then:

$\begin{gathered} \frac{x}{6328}=\frac{100}{20,480} \\ \Rightarrow x=\frac{100\times6328}{20,480}=30.898\ldots \end{gathered}$

To the nearest tenth, 30.898... = 30.9.

Therefore, the markup is equal to 30.9%.
