Question

Tim has m dollars. Rebecca has $6 less than 1/10 times the number of dollars that Tim has. Which expression represents the total amount of money that Tim and Rebecca have? If Tim has $70, how much money do Rebecca and Tim have altogether?

Answer 1

$\text {Tim = m dollar}$

$\text {Rebecca = } \dfrac{1}{10} m - 6$

$\text {Amount of money they have together = } m + \dfrac{1}{10}m - 6$

$\text {Amount of money they have together = } \dfrac{11}{10}m - 6$

If Tim earns $70, then substitute m = 70 into the equation :

$\text {Amount of money they have together = } \dfrac{11}{10} (70) - 6$

$\text {Amount of money they have together = } \ 71$

Answer:
$\text {Amount of money they have together = } \dfrac{11}{10}m - 6$
$\text {Amount of money they have together = } \ 71$

Answer 2

So, Tim has $70, and Rebecca has $6 less than 1/10 of the total money that Tim has.
70 divided by 10 would be 7, then Rebecca has $6 less than the 1/10, which would conclude to Rebecca having $1.
Tim and Rebecca together have a total of $71!
Hope this helped!
