soooooo sorry

Answer 2

Answer:

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 as

2w + 3p = 7.05

eq.1

"The cost of a bag of pretzels is $1.35" can be written as

p = 1.35

eq 2

Together, eq 1 and eq 2 make up your system of equations

To solve, take eq 2 and substitute this value int eq 1

2w + 3 (1.35) = 7.05

2w + 4.05 = 7.05

2w= 7.05 - 4.05

2w = 3

w = 1.5

Hence the cost of a bottle of water is

$1.50
