Question

Ali and Tibor get paid $9 per hour. This week, Tibor made an additional $27 in overtime.

a). Write and expression that represents the weekly wages of Ali and Tibor. Let a represents the number of hours Ali worked this week and let t represent the number of hours Tibor worked this week.


b). Can you write the expression in another way? If so, give an example. Justify your answer.

Answer 1

9a + (9t+27)=x

To write it another way you could flip the numbers around:

(9t+27)+9a=x

Or flip the variable to the other side.

x=9a + (9t+27)

Any way you put the numbers as long as x is on the either side, you will get the same answer.

Hope this helps!
