Tia borrowed $4.55 from her friend on 5 different days. if she makes $15/hour babysitting and she babysits for 3 hours, how much money will tia gave after paying her friend back the money that she owes?

First, we should figure out how much money Tia makes from babysitting, and then we should subtract how much Tia borrowed from her friend to find out how much money Tia will have left after paying back her friend.

To figure out how much money Tia made babysitting, we must multiply how many dollars she makes per hour (15) by the number of hours she babysits (3).

15 x 3 = $45

Now, we should subtract how much money Tia borrowed from her friend.

$45 - $4.55 = $40.45

Therefore, Tia will have $40.45 left after she pays back her friend.

Hope this helps!

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
