D.3x+3y=20

Answer 1

Option no C

Explanation:

Given:

Price of crackers $ 9 for 3 boxes

Price of Granola Bars $6 for 3 boxes

Total bought $ 20 worth of snacks

To find the equation

Solution:

Price of cracker $ 9 for 3 boxes

price of one box of a cracker = $ 9 / 3

=$ 3 per box

Price of granola bars $ 6 for 3 boxes

price of one box of a granola bars = $ 6 / 3

=$ 2 per box

Let total crackers bought are x

price of x crackers will be 3x

Let granola bars bought are y

price of y granola bars will be 2y

as total price is 20

so price of x crackes + y granolas = 20

which will be

3x + 2y = 20

which will be option no C
