1. my little sister, savannah, is three years old. she has a piggy bank that she wants to all. she
started with five pennies and each day when i come home from school, she is excited when i
give her three pennies that are left over from my lunch money. use a table, a graph, and an
equation to create a mathematical model for the number of pennies in the pinay bank on day n.

equation: y=5x+b

table: use equation to calculate 5 x and y values, then arrange them in a simple table

graph: graph table values on a graph

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
