In order to do this you need a system of equations. One equation is going to be about the numbers of people, the other is going to be about the money: what it costs for each type of person and the total amount of money earned. Money and numbers of people are 2 different things so they have to be in 2 different equations. We know that there were children and adults that went to the park and that the total NUMBER of people is 220. That means that adults plus children equal 220 people total. Or, in equation form, a + c = 220. Now the money part. Each child costs 2.25, so the cost of a child is 2.25c; each adult costs 6.20, so the cost of an adult is 6.20a. The total amount of money earned was 890. That equation is 2.25c + 6.20a = 890. Solve the first equation for a: a = 220 - c. Now sub in that value for a in the money equation, like this: 2.25c + 6.20(220-c) = 890. Solve this for c. 2.25c+1364-6.2c = 890. Combine like terms to get -3.95c = -474. Divide both sides by 3.95 to get that c = 120. There were 120 children out of the 220 people that attended. That means that there were 220-120 adults, or 100 adults. There you go!
Answer:
∠CGD is 52°
Step-by-step explanation:
∠AGB is 90° and its corresponding ∠EGD is also 90°
90+38= 128
180-128= 25
Answer:
$24.375
Step-by-step explanation:
Regular price of sandals = $32.50
Store sells sandals for 25% of the regular price.
Hence selling price =(100-25)% of the regular price.
In other words, selling price = 75% of regular price
= 75% of $32.50
= ![\[\frac{75}{100}*32.50\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B75%7D%7B100%7D%2A32.50%5C%5D)
= ![\[24.375\]](https://tex.z-dn.net/?f=%5C%5B24.375%5C%5D)
Hence the sale price of the sandals is $24.375
This is $8.125 less than the regular price of the sandal.
