8m + 3a = 18 Equation 1 3m + 5a = 14.50 Equation 2 Lets multiply equation 1 by 5 and equation 2 by 3 The new equations are: 45m + 15a = 90 9m + 15a = 43.5
Subtract them and get: 36m = 46.5 m = 1.30 Divide both sides by 36
Substitute m into equation 2 (either is fine, but choose the easier one) 3(1.30) + 5a = 14.5 3.9 + 5a = 14.6 Expand the bracket 5a = 10.6 Minus both sides by 3.9 a = 2.12 Divide both sides by 5
Mangoes cost $1.30 Apples cost $2.12 (more like $2.10)
I feel that my working out is wrong, but that is how you work out the answer.
What you have to do first is you have 5 owners correct? Well you take anything they're sharing in this case it's delay/debt, so you divide $110 by 5 and you should get $22. This means that each owner would have to pay $22 to the delay.
