Answer:
The number of A's Dina got = 5/11 × 77 = 385
/11 = 35
Step-by-step explanation:
The number of A's Pete , Chris and Dina received are in the ratio of 4:2:5.
Let the total number of A's = y
Total from ratio = 4 + 2 + 5 = 11
chris A's = 2/11 × y
pete's A's = 2/11 × y + 14 = 4/11 × y
pete's A's
2/11 y + 14 = 4/11 y
14 = 4/11 (y) - 2/11 (y)
14 = 2/11 (y)
cross multiply
2y = 14 × 11
divide both sides by 2
y = 154/2
y = 77
Total number of A's = 77
The number of A's Dina got = 5/11 × 77 = 385
/11 = 35

The answer is C! Have a great day!
Mrs. Dean 150 words per minute, already set up nicely for us
Mr. Kovacs 96 words per 3/4 minute
So we need to adjust 96 words per 3/4 minute to what ever words PER MINUTE.
So, a simple way to do this is change 3/4 to decimal, which would be 0.75 in this case. Knowing that 96 words per 3/4 minute is 25% less than what he would type in a minute, we simply multiple 96 by 1.25 to make up for the 0.25 missing.
Which would get us: Mrs. Dean: 150 wpm
Mr. Kovacs: 96(1.25)=120wpm
Therefore Mrs. Dean types at a greater rate of words per minute, 30 more words per minute to be exact.
