amount of increase=156.60-145=$11.60
Therefore percentage of inrese=(11.60/145)X 100=8%

This is simple. First you would find the difference in change. (156.60-145) Then you would take your answer (11.6) OVER YOUR ORIGINAL PRICE. (145) Now you have 11.6/145. Then you would take that and multiply that by x over 100. Now you have 11.6/145 times x/100. Cross multiply (11.6 * 100) and 145* x. get you product 1160 for 11.6 *100. To get x alone you would divide both sides by 145 and you would get the percent of increase is 8%. You can check that by multiplying .08 (8%) with 145 (the original price) and then add 145 to that. you SHOULD get 156.6.

To rephrase: 156.60 is what percent of 145. 156.60/145 = 1.08. This means 156.60 is 1.08 times 145, or 108% of 145. (Remember, per-cent means 'per-100'.) Thus there is an 8% increase.

$145 is 100%
$156.60 - $145 = $11.60 is the amount increased
$11.60/$145 = 0.08 is the increase as a factor of $145
thus, the price was increased by 8%

[(156.60 - 145)/145]100 = % increase
plug and chug in your calculator and it is 8%
