Since there are 4 quarts in a gallon, 8 quarts equals 2 gallons
Complete the equation of variation where y varies inversely as x and y = 0.125
when x=8
The amount of money each of Mr Mokwebo 's two sons; Tokelo and Refentse will get is R116 and R95 respectively.
<h3>How to write and solve equation:</h3>
- Amount needed to buy chocolate = R253
- Tokelo's money = x
- Refentse's money = x - 21
Total amount needed = Tokelo's money + Refentse's money
253 = x + (x - 21)
253 = x + x - 21
253 = 2x - 21
253 - 21 = 2x
232 = 2x
divide both sides by 2
x = 232/2
x = 116
Therefore,
Tokelo's money = x = R116
Refentse's money = x - 21
= 116 - 21
= R95
