agltan98\" post_id=\"1937823\" time=\"1569565999\" user_id=\"11229:using ur ans $1.53 as original price, lets check the answer again now.
15%->6 egg tarts
100%->40 egg tarts
40+6= 46 egg tarts (ans a)
$61.20 / 40 = $1.53 (ans b)
Check:
If 1 egg tart is $1.53
40 egg tarts should get $61.20
If Jamie got 15% discount,
$61.20 x 15% = $9.18
This extra $9.18 was used to buy 6 more egg tarts. So if I take this extra money divide by the cost of 1 egg tarts, I should get 6 egg tarts:
$9.18 / $1.53 = 6 egg tarts
X has no discount but still spends $61.20, $61.2/$1.53 = 40 egg.
Jamie has a 15% discount and spends $61.20 as well,
price per egg after 15% discount = 1.53 x .85 = $1.3005
Number of eggs Jamie bought = 61.2/1.3005 = 47.0588235
This is not the answer.
The answer should be a) 40 b) 1.8.

Hope this help.
