Answer: There are 5 counters that can be added without having to regroup.
Step-by-step explanation:
Since we have given that
Number of counters = 24
We need to add without having to regroup.
It means that we should make it a prime number which does not get divided by any other number except 1 and itself.
so, After 24, there is other numbers that has chances are as follows:
25,26,27,28,29......
But except 29 all the other number can be regroup as they are composite numbers.
But 29 is the nearest prime number after 24.
So, 24+5=29.
Hence, there are 5 counters that can be added without having to regroup.
Answer:
Jenny save 4 times for the month
Step-by-step explanation:
Given Jenny has saved over the last 12 months.
She saved either or a month.
Let the number of months to save be x
Let the number of months to save be y
Total period is 12 month.
Jenny has saved $3,800 over the last 12 months.
Dividing both side from 50 we get,
Now Multiplying equation 1 by 5 we get,
Now Subtracting Equation 3 by equation 2 we get,
Substituting the value of y in equation 1 we get,
∴ Jenny save 4 Months of and 8 Months of in a 12 month duration
Answer:
4 times
Step-by-step explanation:
Let,
250 = x
350 = y
x + y = 12
250x + 350y = 3,800
Solve the system.
x = 4 and y = 8
Therefore, Jenny saved $250 for 4 months and $350 for 8 months.
