14. Audrey and Belle have some money each. If Audrey spends $18 and Belle spends $24 each day, Audrey will still have $25 left when Belle has spent all her money. If Audrey spends $13 and Belle spends $30 each day, Audrey will still have $139 left when Belle has spent all her money. How much money do they have altogether? [4 marks]
18 : 24 = 3 : 4 = 45 : 60
13 : 30 = 26 : 60
45 – 26 = 19
19 u -- > 139 – 25 = 114
1 u -- > 114 ÷ 19 = 6
105 u -- > 105 x 6 = 630
630 + 25 = $655
They have $655 altogether.
