A vase is bought for $23.50, which includes a profit of 17.5%.
Calculate the amount of profit.

$4.11

Step-by-step explanation:

Given the cost of vase as 23.50 including a 17.5% of profit, this means.

17.5% of 23.5= 17.5/100 × 23.5

= 0.175 x 23.5

= 4.113

Profit amount = $4.1

Hence the amount of profit is $4.1, buying cost = Selling Cost of vase - profit amount

19.39 = 23.50 - 4.113.

I hope this helps.

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5
