4 0

Answer:

14%

Step-by-step explanation:

\frac{70,000}{500,000} :\frac{y}{100}

y × 500,000 = 100 × 70,000

500,000y = 7,000,000

500,000y ÷ 500,000 = 7,000,000 ÷ 500,000

y = 14

KatRina [158]

Answer: The graph of line y= 200+25x represents the given situation.

Step-by-step explanation:

Here, y represents the total calories he takes while x represents ounces of fruit smoothies with his cereal.

And, He knows that a bowl of his favorite cereal with milk has 200 calories.

Also, He also likes to drink a fruit smoothie with his cereal where Each ounce of the smoothie adds 25 calories.

Therefore, y = 200+ 25x  is the total calories he takes after drinking the x ounces  fruit smoothie with his cereal.

The x- intercept of the above line = (-8,0)

And, y-intercept = (0,200)

If x= 1 y=225

If x=-1 y= 175

Therefore, (1,225) and (-1,175) are the point of the above lines

Thus, with help of above information we can plot the graph of line y = 200+ 25x.
