Question

Dino has $1,000 in a savings account that was started for him when he was born. He has a part-time job where he earns $60 each week, and he puts $20 of that into his account each week. An equation could be used to model the amount in his account, y, after x weeks.

Which statements are true about a graph of the equation that will show his account balance during a year? Check all that apply.


A. The x-axis should be labeled from 0 to 12 months since you want to see the change over a year.
B. The x-axis should be labeled from 0 to 52 weekss since you want to see the change over a year.
C. The y-axis should be labeled from $0 to $1,000 since the money in the account will not go above $1,000.
D. The y-axis should be labeled from $0 to $1,300 since the money in the account will not go above $1,300.
E. The y-axis should be labeled from $750 to $1,000 since that is the approximate range of y-values for the year.
F. The y-axis should be labeled from $1,000 to $2,100 since that is the approximate range of y-values for the year.

Answer 1

To model the amount in Dino's account after x weeks, the equation y = 20x + 1000 can be used. The x-axis should be labeled from 0 to 12 months, the y-axis should be labeled from $0 to $1,000, and the y-axis should be labeled from $750 to $1,000 on the graph.

Step-by-step explanation:

To model the amount in Dino's account after x weeks, we can use the equation y = 20x + 1000. Here, y represents the amount of money in his account and x represents the number of weeks. The options that are true about the graph of this equation for a year are:

A. The x-axis should be labeled from 0 to 12 months since you want to see the change over a year.

C. The y-axis should be labeled from $0 to $1,000 since the money in the account will not go above $1,000.

E. The y-axis should be labeled from $750 to $1,000 since that is the approximate range of y-values for the year.
