A customer at the grocery store purchased 27 apples and an unknown number of bananas. The customer purchased a total of 58 apples and bananas. Write an equation with a variable that represents this situation. Explain your process for determining this equation, then solve for how many bananas the customer purchased.

The equation is

(x+27) = 58

Therefore the customer purchased 31 bananas

Step-by-step explanation:

Given, A customer at the grocery store purchased 27 apple and unknown number of bananas. The customer purchased a total of 58 apple and bananas.

Let the number bananas be x

He purchased a total (x+27) apples and bananas.

According to the problem,

(x+27) = 58

⇔x = 58-27

⇔x = 31

Therefore the customer purchased 31 bananas
