Over the weekend, Sally’s Ice Cream Shop was busy! On Saturday, Sally sold 2,998 vanilla ice cream sandwiches and 1,489 chocolate ice cream sandwiches. On Sunday, Sally sold only 1,880 vanilla ice cream sandwiches. Sally estimated that she sold about 6,500 ice cream sandwiches over the weekend. Is Sally’s estimation reasonable? Why or why not? How many ice cream sandwiches did Sally sell in total?

Yes, her estimation is reasonable. If we round up all the number of ice cream she sold, we get 1500 + 1900 + 3000, which is 6400. Her estimation of 6500 is very close. Sally actually sold 6367 ice cream sandwiches.

Step-by-step explanation:

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.
