Answer:

Unit rates are expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.

In the given table shows the number of pictures taken and how much time it took.

For first camera;

Number of pictures (unit rate) per second = \frac{15}{3} =5 pictures.

For second Camera:

Number of picture per second = \frac{48}{8} =6 pictures.

For third Camera:

Number of picture per second = \frac{18}{6} =3 pictures.

The camera that takes picture the fastest is, Second Camera.

(a)

As per the given statement: At Davidson's Bike rentals, it costs $29 to rent a bike for 8 hour.

⇒ unit rate per dollar = \frac{Number of hours }{Total cost} = \frac{8}{29} = 0.2758620 hours

Therefore, 0.227 hours (nearest to hundredths) of bike use does a customer get per dollar.

(b)

Jessica bought 18 pounds of sugar for $10.

unit rate per dollar = \frac{18}{10} =1.8 pounds

therefore, 1.8 pounds of sugar did she get per dollar.

A shirt is on sale for 40% off. The sale price is $12. What was the original price? What was the amount of the discount?
kolbaska11 [484]

x = original price, or 100%

we know then that it original costs "x", which is the 100%, however is discounted by 40%, so the discounted price is really then 100% - 40% = 60%, and we know that that 60% is $12.

if 60% of the original price is $12, what is "x", the 100%?

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 12&60 \end{array}\implies \cfrac{x}{12}=\cfrac{100}{60}\implies \cfrac{x}{12}=\cfrac{5}{3}\implies 3x=60 \\\\\\ x=\cfrac{60}{3}\implies x=20 ~\hfill \stackrel{\textit{amount of the discount}}{20-12\implies 8}\\ ~\hspace{34em}
