Ari received $100 as a birthday gift and has decided to save this
SSSSS [86.1K]

Answer:

Total amount Ari would have saved after 6 months is $220

Step-by-step explanation:

Ari received $100 as a birthday gift and has decided to save this money as well as add $20 of his own money each month. The total money Ari has saved can be estimated using the equation y = 20x + 100, where x is the number of months and y is the total amount of money saved. How much money will Ari have saved after 6 months?

Solution

Given:

g(x) = 20x + 100

where,

x = number of months

g(x) = the total amount of money saved

How much money will Ari have saved after 6 months?

g(x) = 20x + 100

When x = 6

g(x) = 20(6) + 100

= 120 + 100

= 220

g(x) = $220

Total amount Ari would have saved after 6 months is $220
