Interesting problem.
First - let's figure cost of each uniform at purchase.
3,000/40 = $75 each
When some uniforms were returned at $40 - there was a difference of $35 in what they paid and what they rec'd in return. ($75 - 35 = $40)
I think its A not sure though
The expanded form is: 800,000,000+70,000,000+ 6,000,000
The product is the result of multiplication
so the product of 83 and x is : 83x
