Given the statement:
Tiana received three $25 gift cards for her birthday. She wants to buy a new blue-ray player with the gift cards.
Let b represent an expression that will show the amount of money she has left after she buys the blu-ray.
Solution:
In order to determine the equation, we simply needed to put the values in a representation.
Let x = number of gift cards
y = cost of blue-ray player
b = amount of money she has left after buying.
b = 3x - y
Final answer:
b = 3x - y
