Question

Kenny has $1,400 in the bank. He earns $150 every week at his after-school job. What is the rate of change for the scenario described? 2 150 300 1400

Answer 1

The rate of change for the scenario described is $150.

Explanation:

Given that

- Kenny has $1,400 in the bank. This is constant, as we aren't told he withdrew it or from it.

- He earns $150 every week at his after-school job.

Because of this earnings, he gets a new amount of $1,500 plus $150 in his first week, and a multiple of $150 in multiple week.

Example: In week four, he has

$1,500 + (4 × $150)

Week five, he has

$1,500 + (5 × $150)

And so on.

The rate of change for the scenario described is therefore $150

Answer 2

$150

Explanation:

Kenny has $1400 in the bank.

Each Week, he earns $150

At the end of Week 1, His total Income=1400+150

At the end of Week 2, His total Income=1400+150(2)

At any number of week n, His total Income=1400+150n

Therefore, his rate of change in the scenario described is $150
