Question

A travel agent calculates the cost of a trip to Paris using this formula C = p(t + 30).

C is the total cost in pounds

p is the number of people

t is the cost of the trip per person

Use this formula to calculate the total cost if p = 2 and t = 245.

Answer 1

C=550 pounds

Explanation:

Given the formula: C=p(t+30)

and with p=2 and t=245 known.

We can plug our values of p and t into our formula. Once we do this, the only unsolved variable will be C.

C=2(245+30)

Add 245+30 first because they are in parentheses and we must abide by the order of operations.

C=2(275)

Now we just multiply 2(275) because this is all that's left in the formula.

C= 2*275 = 550

We now know that C=550 when p=2 and t=245, but we need to apply units to finalize the answer. We are told that C represents the total cost in "POUNDS", so pounds is our units for variable C.

Our final answer is...

C=550 pounds
