Answer 1

Php630

Explanation:

2 boxes of chocolates cost Php180.

Number of boxes : price

2 : 180

How much do 7 boxes of chocolates cost?

Let x = price of 7 boxes

Number of boxes : price

7 : x

Number of boxes : price

2 : 180 = 7 : x

2/180 = 7/x

cross product

2*x = 180*7

2x = 1,260

Divide both sides by 2

x = Php630

7 boxes of chocolates cost Php630
