Answer:
After 5 months, both options will have saved 450$
Step-by-step explanation:
The first option can be modeled with the expression
400 + 10x
The second option can be modeled with the expression
300 + 30x
The variable x represents the months so in order to find the month where Tina saves the same amount, we set the expressions equal to each other.
400 + 10x = 300 + 30x
solve for x
20x = 100
x = 5
After 5 months, Tina will save the same amount of money which is
400 + 10*5 = $450
