Andrea has six times as many dimes as quarters. if her dimes and quarters total $12.75, how many of each coin does she have?

Salsk061 [2.6K]

Since the question is asking for the no. of coins each, we can represent the numbers with variables.

number of quarters = x
number of dimes = 6x (because there as 6 times as many dimes as quarters)

Next we can multiply the variables by the value of each coin.

25x + 6(10)x = 1275
25x + 60x = 1275
(make sure the expressione quals 1275, not 12.75. A dime is not 10 dollars, nor is a quarter 25 dollars).
85x = 1275
x = 15

Now that we have the value for x, plug it back in.
Andrea has 15 quarters and 90 dimes.

A parking garage in the city charges $2.75 for the first hour and S1 25 for each additional hour or part thereof. What is the ma

Korolek [52]

Answer: The first hour is free, and the rest charges is $2.50

Let x be the time.

Let y be the total

Your equation will look like

When x < 2, y = 0

When x > 1, y = $2.50(x)

So:

1 < x < ∞ for hours, then equation will look like:

y = total amount

$2.50 is cost (remember that the first hour is for free, and so you subtract $2.50 from the total.

$2.50x - $2.50 = y should be your equation.

hope this helps

<h3>What is a frequency distribution?</h3>

A frequency distribution is a pictorial or graphical representation that shows the number of observations of each categorical value (a group of values) that occurs.

By showing the frequency counts for each category, it becomes easier to determine and interpret the presented information based on their relative frequencies.

Frequency charts, tables, or graphs are used to display frequency distributions of data.
