Answer:
£152.40
Step-by-step explanation:
If he made 80 cakes at a ratio of 3:2:5, then he made:
24 chocolate cakes
16 lemon cake
40 fruit cakes
He sold all of the chocolate: 24x2=48
He sold 3/4 of the lemon: 3/4 of 16=12 12x1.70=20.40
He sold 7/8 of the fruit cakes: 7/8 of 40=35 35x2.4=84
48+20.40+84=152.40
