One tennis ball can holds 3 balls. Jenna filled 5 cans and had 1 ball left over.

Which equation could we use to find n, the number of tennis balls?

Answer 1

You can you the
`y=mx+b` formula by substituting
`16=3(5)+1`

Explanation:

g = groups of tennis balls

one can can hold 3 tennis balls

plus we have 1 let over

so you can use an equation like this:

`3g+1=` number of tennis balls

So we know how many tennis balls fit into one can and we know the left over amount:

`3(5) + 1 = 16`

She had 16 tennis balls in total.

Its essentially a y=mx+b equation but replace: x with the number of cans, m with the amount of tennis balls that goes into each can, and b with the left over tennis balls.

`y=mx+b\\y=3g+1\\y=3(5)+1\\y=15+1\\y=16`

And y would be the amount of tennis balls we have in total.
