Answer:
A) $8/bushel (divide dollars by bushels)
B) $2
Step-by-step explanation:
A) We observe that the graph is a straight line through the origin, so we know the price is proportional to the quantity. The "rate of change" is the ratio of price to quantity, which can be figured using any point on the graph.
For easy division by quantity, it is convenient to use the point for 10 bushels. That price is $80, so the "rate of change" is ...
price per bushel = $80/10 = $8 . . . per bushel
__
B) The same calculation can be done for the previous year. Any line of the table will do.
price per bushel = $12/2 = $6
The current year price is greater by ...
$8 -6 = $2 . . . per bushel
Answer:
A's received by Dina is 35.
Step-by-step explanation:
Given
number of A’s received by Pete, Chris, and Dina on their report cards were in a ratio of 4:2:5.
Let the
A's received by Pete = 4x
A's received by Chris = 2x
A's received by Dina = 5x
This, is done so that ratio of 4:2:5 remains intact.
Now, given Pete got 14 more A’s than Chris got
Thus, writing it mathematically
A's got by Pete = A's got be Chris + 14
we will be using A's got Pete and Chris in term of x as defined above
4x = 2x+ 14
=> 4x - 2x = 14
=> 2x = 14
=> x = 14/2 = 7
A's received by Dina = 5x = 5*7 = 35( Answer).
