The science club is selling puzzles to raise money. The supplier chargers a one time fee of $55 for each order and $10 for each puzzle. Write and solve an equation to find the number of puzzles the science club can buy if they have $1,245.

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

find the magnitude of the trig term  

csc

(

x

)

−

1

by taking the absolute value of the coefficient.
