Are my answer correct

my answer are 3.15 per lb and. 2.50 per lb

and the problem for the 1st one and 2nd one is

1. 10.50 / (3 1/3=10.50 / ( 10/3)=10.50* 3/10=31.5/10=3.15 per Ib

2. 6.25 / (21/2)= 6.25 / ( 5/2)= 6.25* 2/5 = 12.5 / 5 = 2.50 per lb

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380
