Accepted Solution

A:

Step-by-step explanation:let w be the cost of a bottle of water and p be the cost of a bag of pretzels"2 bottles of water and 3 bags of pretzels is $7.05" can be written as2w + 3p = 7.05 Β Β ------------- eq.1"The cost of a bag of pretzels is $1.35" can be written asp = 1.35 ------------- eq 2Together, eq 1 and eq 2 make up your system of equationsTo solve, take eq 2 and substitute this value int eq 12w + 3 (1.35) = 7.052w + 4.05 = 7.052w = 7.05 - 4.052w = 3w = 1.5Hence the cost of a bottle of water is $1.50
