A caterer charges a fixed amount for preparing a dinner plus a rate per student served. The total cost is modeled by this equation: Total cost= Fixed amount + Rate • Number of students

Paula knows that the total cost for 250 students will be $1375 and the total cost for 350 students will be $1725 find the caterers fixed cost and the rate per student so explain how you figured this out or show your work to justify your answer

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
