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?

a. x = (C — 60) / 85

bi. 3

bii. 5

Step-by-step explanation:

a. C = 85x + 60

C — 60 = 85x

x = (C — 60) / 85

bi. When C = $315,

x = (C — 60) / 85

x = (315 — 60) / 85

x = 225/ 85

x = 3

bii. When C = $485

x = (C — 60) / 85

x = (485 — 60) / 85

x = 425/ 85

x = 5

35 is an outlier

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
