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).
