Maria opens a savings account with $50 and then saves
an additional $20 per month. After 6 months, her savings account balance is $170.
To find the total amount saved in 6 months, we need to calculate the monthly savings and add it to the initial deposit:
Monthly savings = $20
Initial deposit = $50
Total savings = (Monthly savings x Number of months) + Initial deposit
Total savings = ($20 x 6) + $50
Total savings = $120 + $50
Total savings = $170
So, Maria saves a total of $170 in 6 months.
