A shopkeeper makes a profit of 15% by selling a book for $230. What is the cost price and the actual profit?

Cost price = 200

Profit = 230-200 = 30

Step-by-step explanation:

x + 15/100x = 230

x + 3/20x = 230

20x + 3x = 4600

23x = 4600

x = 200

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
