Answer:
the answer is 28d + 42
Step-by-step explanation:
multiply what's on the brackets them add
Only two numbers less than 100 have a factor of 40: 40 (1 x 40) and 80 (2 x 40). Since 40 is a factor of both 40 and 80, 10 must also be a factor - indeed, 40 = 4 x 10 and 80 = 8 x 10.
The two number must be 40 and 80.
You need to do 120-60=60 and that means he only needs $60.
I think you forgot to add the other part of the question
