An investor invests $500 in a certain stock. after the first six months, the value if the stock has increased at a rate of $20 per month. sketch a graph that represents the situation.

We know that:

Based on this, we can make a table and then graph. x variable is gonna be months, and y variable is gonna be the money. We just need to write six months, and each month increase $20. The initial condition is x=0, in this moment, the money is $500.

x      y

0     500

1      520

2     540

3     560

4     580

5     600

6     620

Remember that each pair represents a point to graph the function.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
