Question

A pencil costs 2.50 and a pen costs 3.70. Jessica bought x pens and y pencils. Write an algebraic expression for the total amount she spend

Answer 1

2.50x+3.70y = t

Explanation:

T = total

x = pen

y= pencils

we put the prices in front of the variables for the items and it will look like this jessica is going to buy x amount of pens that cost 3.70 per pen. Or jessica is buying pencils for 2.50 per y amount of pens her total will be a combination of her prices
