Respuesta :

Answer

4a. D = 50 + 20W

4b. (3, 110)

Explanation

4a. The equation that represents the relationship between the dollar amount and the number of weeks of saving is

[tex]D=50+20W[/tex]

Where;

D is the Amount n dollar in her bank account,

W is the number of weeks of saving.

4b. The coordinates of the point on the line that represents the amount in savings after 3 weeks implies substituting W = 3 into the relation above

[tex]\begin{gathered} D=50+20(3) \\ D=50+60 \\ D=110 \end{gathered}[/tex]

Hence, the coordinates are (3, 110)
