1the admission fee at a small fair is $1.50 for children and $4.00 for adults. on a certain day, 2,200 people enter the fair and $5,050 is collected. which of the following systems of equations would represent this scenario?
a a + c = 2,200 1.5a + 4c = 5,050

b a + c = 5,050 1.5a + 4c = 2,200

c a + c = 2,200 4a + 1.5c = 5,050

d a + c = 5,050 4a + 1.5c = 2,200

It’s hard to understand what you put.. can you show a picture ?

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
