Answer:
74 and 27
Step-by-step explanation:
let x and y be the numbers
x + y =101........eqn 1
x - y = 47.......eqn 2
solve simultaneously
from equation 2, make x the subject
x= 47 + y........eqn 3
put eqn 3 into eqn 1
(47+y) + y = 101
47 + 2y = 101
2y= 101 - 47
2y=54
y= 54/2
y= 27
put y=27 into eqn 3
x = 47 + 27
x = 74
2:3:7...added = 12
green pepper : 2/12(36)....1/6(36) = 6 cups
onion : 3/12(36)....1/4(36) = 9 cups <==
tomato : 7/12(36) = 21 cups
47.50/10 = 4.75
57/12 = 4.75
76/16 = 4.75
The unit rate is C. $4.75
