The total amount spent on these cards is $379.5 if ninety of the cards they send cost $2.20 each. Thirty-nine of the cards cost 2.90 each. The remaining 36 cards cost $1.90 each.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
A company bought New Year’s getting cards to send to it valued customers. Ninety of the cards they send cost $2.20 each.
Let x be the total amount spent:
x = 2.20×90 + 39×2.90 + 36×1.90
x = $379.5
Thus, the total amount spent on these cards is $379.5 if ninety of the cards they send cost $2.20 each. Thirty-nine of the cards cost 2.90 each. The remaining 36 cards cost $1.90 each.
