Answer:
c. Both options A and B will allow him to meet his goal
Step-by-step explanation:
Total Amount Drake wants to save = $ 750
Amount he will save each week = $ 125
Amount gathered after 4 weeks = $ 470
If he followed the inital plan, the total amount after 4 weeks would have been = 4 x 125 = $ 500
So, after 4 weeks he is $30 short of his target.
Plan A:
Stay with saving the original amount each week but take the class a week later than originally planned
This way Drake would have 3 more weeks to save money each with a saving of $125. So total money accumulated would be:
$ 470 + ( 3 x $125 ) = $ 845
Which is above $ 750, so he would easily meet his goal through this plan
Plan B:
Increase the amount of money he saves each week by $15 from his original plan
He will have 2 weeks remaining. The saving in each week will be:
125 + 15 = $140
So the total saving after 6 weeks will be:
470 + 2 x 140 = $ 750
which is the exact amount he needs for the class. So he will meet his goal using this plan as well
So, option C gives us the correct answer. Both options A and B will allow him to meet his goal
