Answer:
pencils=$4
pen=$1.5
Step-by-step explanation:
Step one:
given data
let pencils be x and pens be y
Mara bought 8 boxes of pencils and 3 packages of pens for $24
8x+3y=24------------1
Elaine bought 4 boxes of pencils and 6 packages of pens for $30
4x+6y=30------------2
solve 1 and 2 simulteneoulsy
8x+3y=24---------X1
4x+6y=30----------X2
subtract the answer bellow
8x+3y=24
8x+12y=60
0-9y=-36
divide both sides by- 9
y=36/9
y=$4
put y= 4 in 1
8x+3*4=24
8x+12=24
8x=24-12
8x=12
divide both side by 8
x= 12/8
x=3/2
x= $1.5
Not enough information. The question doesn't say how much one quart of paint covers.
EDIT: here's the solution
we have to find the total area of the 4 walls and subtract the area of the door. there are 2 walls with dimensions 16 by 10, and 2 walls with dimensions 16 by 12. so we have: 2(16*10)+2(16*12)=320+384=704 for the area of the walls. now, we can find the area of the door which is 3*8=24. <span>so we subtract the area of the door from the area of the walls, so we have: 704-24=680. </span><span>Since a quart of paint covers 100, then we divide and get 680/100=6.8 but since we need a whole number of quarts, we round up to get 7 quarts of paint. </span>
