Hello.

From our initial value, the price is $21 for 1 hour. After this, each hour is $14 more. From this information, we can solve for how much parking would cost at 24 hours, or one day.

5, 77; 6, 91; 7, 105; 8, 119; 9, 133; 10, 147; 11, 161; 12, 175; 13, 189; 14, 203; 15, 217; 16, 231; 17, 245; 18, 259; 19, 273; 20, 287; 21, 301; 22, 315; 23, 329; 24, 343.

After 24 hours, the total price will be $343.

I hope this helps!

The actual length of Lake Superior is 350 miles and the width is 160 miles. What's the length and width of the lake on a map if
pentagon [3]

The correct option is:   B.  length: 14 cm, width: 6.4 cm

<em><u>Explanation</u></em>

The actual length of Lake Superior is 350 miles and the width is 160 miles.

The scale is given as:  1 cm = 25 miles

Suppose, the length and width of the lake on the map are  x cm and y cm respectively.

First, the equation according to the <u>ratio of scaled length to the actual length</u> will be....

\frac{x}{350}=\frac{1}{25}\\ \\ 25x=350\\ \\ x=\frac{350}{25}=14

Now, the equation according to the <u>ratio of scaled width to the actual width</u> will be....

\frac{y}{160}=\frac{1}{25}\\ \\ 25y=160\\ \\ y=\frac{160}{25}=6.4

Thus, the length and width of the lake on the map will be 14 cm and 6.4 cm respectively.
