Answer:
12 girls
Step-by-step explanation:
40 times .30
In general, a maximum of 25% to 30% of one's gross income can be spent on rent. So, according to this lets find out the values.
Given is,
The gross annual salary of Kathleen = $56820
So, her monthly income becomes = 
So, its 25% is =
= 1183.75
And 30% becomes =
= 1420.50
If we take an average of both, as the value will lie between these two figures we get, (1183.75+1420.50)/2 = $1302.12
Hence, this value lies close to $1326. So, the answer will be option B - $1326
Answer:
4 students
Step-by-step explanation:
As shown in the diagram, let U=[The total number of students questioned]

A=[Those who liked peanut butter ]

B=[Those who liked jam ]

x = those who like both peanut butter and jam.
Also 6 liked neither peanut butter nor jam.
From the diagram we can write the mathematical equation as follow and solve for x


We add x and subtract 30 to both sides.


Therefore 4 students like both peanut butter and jam.
C= 14.88x+8.88y
