Answer:
Neither option A nor option B will allow them to meet their goal.
Step-by-step explanation:
Consider the provided statement.
Mike plans to save money for their wedding over a 20 month period. They will need to save $8,000 to help pay for the wedding.
After a year they saved $4,000.
That means in 12 months they need to save $4000.
So, in 1 month they saved 4000/12 = $333.3
Now they have 8 months because 20 - 12 = 8 months.
To save $8000 they need to save $4000 in remaining months.
Consider the provided options.
Option A: Stay with saving the same amount they've been saving each month but postpone the wedding 2 months.
If they save the same amount and postpone their wedding by 2 month then they will have 8 + 2 = 10 months.
They need to save $4000 in 10 months.
They can save $333.3 each month so in 10 months they can save:
$333.3 × 10 = $3333.3
Which is less than $4000.
So option A will not work.
Now consider the option B. Increase the amount of money they save each month by $80 from what they've been saving.
Previously they was saving $333.3 Now increase the saving by $80
$333.3 + $80 = $413.3
The number of month they have is 8.
The total savings in 8 month is: $413.3 × 8 = $3306.4
$4000 + $3306.4 = $7306.4
Which is less than $8000.
So option B will not work.
Hence, Neither option A nor option B will allow them to meet their goal.
