Apencil 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

2.50x+3.70y = t

Step-by-step 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

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
