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.
Answer: approximately 5.5814 calories
==================================
We start off with this ratio
4.3 ounces : 24 calories
Divide both parts of the ratio by 4.3 so that we end up with 1 ounce on the left side
4.3 ounces : 24 calories
4.3/4.3 ounces : 24/4.3 calories
1 ounce : 5.5814 calories
This value is approximate to four decimal places.
The two equations:
Daisy’s: y = 4x + 14
Donald’s: y= 2x + 26
The point of intersection is (6, 38)
This point refers to how many of passengers it will take for both equations to have have the same cost output.
Daisy’s deal is better if you have less than 6 passengers. We can tell because the line for the equation is lower than Donald’s line. Donald’d deal will be better if you have more than 6 passengers since the line is lower than daisy’s deal.
