S=12+7D

Step-by-step explanation:

Linear relationships.

The initial amount of money Ethan has is $12. Each day, he adds up $7 to his savings. At a given day D after his initial funding, he will have added $7D, and he will have in his piggy bank

S=12+7D

For example, on the day D=30 he will have

S=12+7 (30) = $222
