Answer:
450 portugals
Step-by-step explanation:
in this question, we are tasked with calculating the number of portugals which are picked by the farmer
Firstly, let the number of portugals picked be p and the number of oranges picked be r.
Thus;
p + r = 600 ••••••••••(i)
Secondly there are 3 times as many oranges as there are portugals;
That would be;
3 * r = p
3r = p. •••••••••(ii)
substitute ii into i
3r + r = 600
4r = 600
r = 600/4
r = 150
P = 3r
p = 3 * 150 = 450
Original cost = $16.40
Tax=9℅
Tip=20℅
Total cost is,
=16.40+ 16.40×9℅+ 16.40×20℅
=16.40 +16.40×9 /100+16.40×20 /100
= 16.40+1.476+3.28
=$21.156
6.9 is greater than 1.2
