Answer:(1)Donna = Pounds 180Kyra = Pounds 240(2)Kelly = Pounds 225Nelly = Pounds 175Step-by-step explanation:(1)Donna = xKyra = x + 60If Donna spends 1/3 of her money she is left with 2/3 of her money;2/3 x Kyra now has twice as much money as Donna can be represented as; X + 60 = 2 * 2/3 xX + 60 = 4/3 x (x + 60)3 = 4x3x + 180 = 4x180 = 4x β 3x180 = xDonna = 180Kyra = 180 + 60 = 240(2)Kelly = xNed = yKelly spends 40% of her money. Therefore he is left with 60%;60/100 xNelly spends Euros 40 of his money. Therefore he is left with;y- 40If they now have the same amount of money;60/100 x = y β 403/5 x = y β 403x = 5y β 2003x β 5y = -200 Remember Kelly & Ned has Euros 400 in total;x + y = 400Now we can solve the simultaneous equation by substitution;x + y= 4003x β 5y = -2003x + 3y = 1200-3x β 5y = - 200=8y = 1400Y = 175X = 225Kelly = 225Nelly = 175Learn More:
