Two business partners, ellen and bob, invested money in their business at a ratio of 3 to 7. bob invested the greater amount. the total amount invested was 200 dollars. how much did each partner invest?

Ellen invested $60 and Bob invested $140

Step-by-step explanation:

let the two amounts invested by 3x and 7x

(notice 3x : 7x = 3 : 7 )

then 3x + 7x = 200

10x = 200

x = 20

then 3x = 3(20) = 60

and 7x = 7(20) = 140

60+140=200

the answer would be c:   ax + b = ax + c
