Answer 2

Cost of each mountain dew is 1.09 Rs.

Step-by-step explanation:

Given:

Kait bought 5 mountain dews and 7 bags of cheetos for Rs. 16.58

Alia bought 3 mountain dews and 6 bags of cheetos for Rs. 12.81

To find out:

The cost of each mountain dew

Solution:

Let the cost of each mountain dew be x and the cost of each bag of cheetos be y

Then,

According to the question

5x + 7y = 16.58               (1)

3x + 6y = 12.81                (2)

Multiplying eq (1) by 6 and eq (2) by 7 and subtracting eq (2) from eq (1)

(30-21)x = (16.58 × 6) - (12.81 × 7)

or, 9x = 99.48 - 89.67

or, 9x = 9.81

or, x = 9.81/9 = 1.09

Therefore, the cost of each mountain dew is 1.09 Rs.
