BRAINLIEST Please!!!!

Step-by-step explanation:

Answer 2

C = # of children and charged $3.50 each

A = # of adults and charged $9.00 each

($3.5 x C)+ ($9.0 x A) = $1505

(this represents the total amount of money collected)

A + C = 210 (total number of people who got in)


So now you have two equations and two unknowns - so you can solve it via substitution.


A = 210 - C

Put this term for C into the other equation

3.5*C + 9*(210-C) = 1505

3.5C + 1,890 - 9C = 1505

385 = 5.5C

C = 385/5.5

C = 70 Children


A = 210 - 70

A = 140 Adults



Find the graph where the lines intersect at those two numbers
