Mary has $ 3.00 more than Ben but $ 5.00 less than Jane. If Mary has $ x, how much does Jane and Ben have altogether?
$(2x-8)
$(2x+8)
$(2x-2)
$(2x+2)

Explanation

Mary(m),

Ben(b)

Jane(j)

m = b +3 

m = j - 5

where m = x

b = x - 3 and j = x + 5

b+ j → x - 3 + x + 5

= 2x +2 

Jane and Ben have $(2x+2)
