The amount he spent at the convenience store can be represented by x. He spent four times more at the bookstore than he did at the convenience store. Mike spent a total of $27.50 at both stores. What is x, the amount Mike spent at the convenience store?

Step-by-step explanation:

Amount spent by him at convenience store = $x

amount spent by him at book store = $4x

total amount spent by him at both store = $27.50

according to the question

x+4x = 27.50

5x = 27.50

x = 27.50 /5

x = 2750/(5×100)

x = 2750/500

x = $5.5

hence, the amount mike spent at the convenience store is $5.5

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
