Question

Arnold reads an average of 21 pages each day. Write an equation to represent the number of pages after many numbers of days. What is the equation in this word problem?

Answer 1

Answer:

Let X be number of days

Let Y be total amount of pages

21x=y

Step-by-step explanation:

So we know that Arnold reads 21 pages a day

But we don’t know how many days

THe number of pages can change expending on the amount of days he reads

So lets make that y.

So 21x=y is the equation unless they ask for different interpatations of the variables (x,y,z)
