Answer:
Step-by-step explanation:
Answer:
an = 4n - 1
a1 = 3
a2 = 7 = 3 + 4
a3 = 11 = 3 + 4.2
a4 = 15 = 3 + 4.3
a5 = 19 = 3 + 4.5
.....
=> this is a arithmetic with a1 = 3 and d = 4
=> an = 3 + 4(n - 1) = 4n - 1
Answer: 140%
Step-by-step explanation:
First, you must find out how much you'll be making. To do this, multiply 356 by .4 (to get 142.4). If you're making 40% profit, you must add 142.4 to 356 (or else you'd be losing money!). We now know whoever sold these bike racks made 498.4 dollars. Divide this by 356 and get 1.4 which converts to a 140% markup up price (also meaning the price the racks were sold at is 1.4 times the price bought).
Hope this answers your question! Best of luck.
