1. 50A + 25B = 1500, where A is the number of items type A sold, and B is the number of items type B sold.

2. d=distance, t=time, s=speed
d=st (distance equals rate (speed) times time)

3. y = 250 + 0.02x, where x is the dollar value of sales made and y is total income

4. V = 36 – 3.4t, where V is the value in thousands of dollars.

OK
1) Let no of itemA = a
Let no of itemB = b
Then 50a + 50b = 1500

2) D = s x t
So 540 = s x 3

3) y = 250 + 2% of x

4) DEP for 1 year = (36000-2000)/10
= 3400
So V =36000 – (3400 x t )

wow, this is long. You want someone to do your homework or something? You should do your own homework. Otherwise, you won’t be able to learn.
