The first equation has to be the sum of hotdogs and hamburgers. Since a total of 300 <span>hamburgers and hotdogs was sold, the first equation is:
h+d=300
Now, the second equation is about the money. They say that EACH hamburger cost $2 and each hotdog cost $1. And, the total amount of money made was $420. So the second equation is:
2h+d=420
SO, overall, the system of equations is this:
h+d=300
2h+d=420

Answer:1.56
Step-by-step explanation:
For constant of proportionality of k,
y=(1/k)*x
If y =9,
9=7/k
K=7/9=0.78
y=0.78x
y=0.78*2=1.56
When x
Answer:
A. $11.75
B. $1.75x + $1.00y = c (cost)
Step-by-step explanation:
A. Because apples cost $1.75 each you could multiply the amount of apples you intent to buy by $1.75 which in this case the amount of apples wanted is 3. $1.75 x 5 = $8.75. You would do the same thing for the peaches except the amount per peach is different. $1.00 x 3 = $3. Then you would add the two amounts together to get the amount Brooklyn and her friend would have to pay. $8.75 + $3 = 11.75
B. Because you multiply the amount of items you intend to get by the cost per item the equation you would follow if the amount of items changed would be. $1.75x + $1.00y = c (cost)
Hope this helps!
Please tell me if I am incorrect I enjoy learning from my mistakes!
Good luck!!
