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).

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
