After the Raptors’ championship parade, Drake needed a facility for his “Raptors championship party”. Jurassic Park charges $1500 for the facility and $20 per meal.
Inside, Scotiabank Arena charges $1000 for the facility and $25 per meal.
a) Write an equation to represent the cost for Jurassic Park.
b) Write an equation to represent the cost for Scotiabank Arena.
c) Solve the linear system to find the number of guests for which the charges are the
same at both facilities.
d) What is the cost of both facilities in question “c”?

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
