Question

Mike wants to buy a new basketball.In order to save enough for the new basketball he is going to add $10 a week to his savings.He has already saved up $9.Use w to stand for the number of weeks and t for the total amount of money he has.Write an equation for calculating the total (t) for any number of weeks (w).

Answer 1

The expression represents the total amount of money Mike earned for both weeks is 2.05x dollars

Solution:

Given that, Mike earned x dollars the first week of his new job

He earned 5% more the second week than the first week

To find: Total amount earned in both weeks

From given,

Amount earned in first week = "x" dollars

Amount earned in second week = 5 % more than first week

Therefore,

Amount earned in second week = x + 5 % of x

Thus amount earned in second week = 1.05x dollars

The total amount earned in both weeks:

Total amount = Amount earned in first week + Amount earned in second week

Thus the expression represents the total amount of money Mike earned for both weeks is 2.05x dollars
