Ellen buys 5 videos that each cost c dollars a dvd for $30 and a cd for $20. write an expression in simplest form that represents the total amount spent

5c+50

Step-by-step explanation:

5c comes from the 5 videos that cost c dollars. 50 is when you add the $30 for the DVD and $20 for the CD together. You add those up to get the answer, but you'll have to solve for c first, then you can solve it.

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
