See explanation and results below.
Step-by-step explanation:
We have the following data:
Age (yr) when award was won Frequency 25-34 31 35-44 36 45-54 12 55-64 4 65-74 6 75-84 1 85-94 2
If we order the data we got the following result. We assume that the midpoint is given by:
The
And the limits are given by the lower and upper limit.
L.Limit U.Limit Class W Midpoint Frequency Limits
25 34 34-25=9 29.5 31 [25-34]
35 44 44-35=9 39.5 36 [35-44]
45 54 54-45=9 49.5 12 [45-54]
55 64 64-55=9 59.5 4 [55-64]
65 74 74-65=9 69.5 6 [65-74]
75 84 84-75=9 79.5 1 [75-84]
85 94 94-85=9 89.5 2 [85-94]
Every week he withdraws $35 from the $950 in his savings, and he wants at least $600 by the end of the summer. So we could write:
Where 'x' is the number of weeks. Now let's solve it for 'x'.
Subtract 950 to both sides:
Divide -35 to both sides, don't forget to switch the sign when dividing/multiplying by a negative number:
So he can only withdraw at money for at most 10 weeks if he wants at least $600 left in his account.
