A store having a sale on chocolate chips
1 answer:
Answer:
chocolate chips: $3.75
walnuts: $2.5
Step-by-step explanation:
lets say chocolate chips cost x dollars and walnuts cost y dollars. we then have
6x + 5y = 35
2x + 3y = 15
multiply the second equation by 3 to get 6x + 9y = 45
subtract the 1st equation from the new equation to get 4y = 10, so y=$2.50
plug this value into the 2nd equation to get x=$3.75
