Question

Jane deposits coins into her piggy bank each day. On the first of the month, Jane deposits 11 coins. Each day after that she deposit 7 more coins. What is the equation that defines how many coins she deposits after the nth day?

Answer 1

11 + 7n

Explanation:

Here, we want to write an equation that represents the the number of coins deposited after the nth day

Mathematically,

there are 11 coins

We now proceed to add;

7 * n = 7n to what we have

So finally to get the number of coins , we add up

That will be:

11 + 7n
