The correct answer is y=2/3x+4 which is the last option :)
Your answer should be 76/45
Let the number of sodas sold be x and the number of hotdogs sold be y. We can assemble a system of equations from the information given and solve.
x+y=170 (We know that soda + dogs is 170)
x-50=y (We know that dogs is equal to 50 less than sodas)
We can use substitution to solve this system of equations.
x+y=170
Sub in the value of y from the second equation
x+(x-50)=170
2x-50=170
2x=220
x=110
We now know the number of sodas sold was 110. Lets now plug this value into the equation to solve for y.
x+y=170
110+y=170
y=60
So, there were 60 hotdogs sold and 110 sodas sold.
So the number of pencils bought can be represented by an equation:
, where n is the number of notebooks bought. Since Helen bought 5 notebooks, simply plug 5 into n:
. So Helen bought 12 pencils.
