Part 1 of 2 Swimming Pool On a certain hot summer's day, 603 people used the public swimming pool. The daily prices are $1.50 for children and $2 25 for adults. The
receipts for admission totaled $1126,50. How many children and how many adults swam at the public pool that day?

Fgfbekbkdbe i appreciate it very much

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
