the total cost c (in dollars) to participate in a ski club is given by the literal equation c=85x+60, where x is the number of ski trips you take.

a. solve the equation for x.

b. how many ski trips do you take if you spend a total of $315? $485?

41/2 - 1 1/3 what is the answer as a fraction?

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
