The total cost cc (in dollars) to participate in a ski club is given by the literal equation c=85x+60c=85x+60, where xx is the number of ski trips you take
how many ski trips do you take if you spend a total of $315? $485?

The total cost C (in dollars) to participate in a ski club is given by the literal equation :

Where x is the number of ski trips you take.

1. When C = 315 ;substituting the value of C in the above equation.

=>

=>

x = 3 trips.

2. When C = 485

=>

=>

x = 5 trips.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
