Question

Priya starts with $50 in her bank account. She then deposits $20 each week for 12 weeks Shown is the graph of your equation: y = 50 + 20x from the last slide. Write the coordinate pair format: (x,y) that represents the amount in after 3 weeks.

Answer 1

Given data:

The given expression y=50+20x.

Here, x is the number of weeks.

Substitute 3 for x in the above expression.

y=50+20(3)

=50+60

=110

Thus, the coordinate pair is (3,110).
