Money invested S + B = $5000 - - - - (a)
Money earned can be represented in S & B as follows:
0.07*S + 0.14*B =$500 - - - - (b)
Equations a & b are two equations with two unknowns.
From equation a:
S = 5000 - B
Replace S in equation b
0.07*(5000 - B) + 0.14*B =$500
0.07B = 500 - 350 = $150
B = 150/0.07 = $2142.86
S = 5000 - 2142.86 = $2857.14

Answer:
Speed = Distance/Time. so if you rearrange this it means that you get Time = Distance/Speed. Therefore 240/60 = 4 then you just think of doing miles(distance)/Miles per hour(speed) which leaves you with 4 hours which=C
Step-by-step explanation:
Sometimes to make it easier i use a triangle from this equation, you cover up what one you want and then you do what it says. If you cover up distance then you are left with speed x time. Likewise if you cover up speed. Speed = Distance / Time.
