Question

Owen receives $10 and puts it into his savings account. He adds $0.50 to the account each day for a number of days, d, after that. He writes the expression 10 + 0.5(d – 1) to find the amount of money in his account after d days. Which statement about his expression is true?

Answer 1

well it depends on the number of days but here's how you do it. you use d as a substitute for the number of days so....

10+0.5(d-1)= 10+0.5(1-1)=10

10+0.5(d-1)=10+0.5(2-1)=10.5

10+0.5(d-1)=10+0.5(3-1)=11

and you just keep on plugging the next number up in replace for d for the number of days that there are.

I hope this helped.....
