The cost of a jacket increased from $75.00 to $87.75. what is the percentage increase of the cost of the jacket?

1) we have to calculate the increase of the cost of the jacket.
Increase of the cost of the jacket=new price - previous price
increase of the cost of the jacket=$87.75 - $75.00=$12.75

2)Now, we calculate the percentaje incresae of the costo of the jacket by the rule of three.
$75=100%

$75100%
$12.75      x

x=($12.75 * 100%) / $75=17%

the percentage increase of the cost of the jacket is 17%

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
