The price for 7 bags of trail mix and 4 bananas is 15.45 dollars.
The expression for x trail bag and y bananas is 1.35x + 1.50y.
<h3>How to represent expression?</h3>
In maths, an expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.)
Therefore, the cost of a bag of trail mix at the corner store is 1.35 dollars and the cost of a banana is 1.5 dollars.
The cost for 7 bags of trail mix and 4 bananas can be computed as follows;
let
x = bags of trail mix
y = number of banana
Therefore,
1.35x + 1.50y
1.35(7) + 1.50(4) = 9.45 + 6 = 15.45
Therefore, let's find the expression for x trail bag and y bananas.
Hence,
1.35x + 1.50y
