Answer:
x ≤ 4.9
Step-by-step explanation:
5x +1/2≤ 25
Multiply each side by 2 to get rid of the fractions
2(5x +1/2)≤ 25*2
10x +1 ≤ 50
Subtract 1 from each side
10x+1-1 ≤50-1
10x ≤ 49
Divide by 10 on each side
10x/10 ≤ 49/10
x ≤ 4.9
15+25= 40

Step-by-step explanation:
im so sorry if im wrong, also start using m4thway for problems like these! it shows you the steps and everything.
(the 4 is an a bc they wouldnt let me put the name of it)
Pen=x
Pencil=y
y+0.15=x
y+x=0.69
y+y+0.15=0.69
2y=0.69-0.15
2y=0.54
y=0.54/2
y=0.27 pencils
y+0.15=x
0.27+0.15=x
0x=0.42 pen
150 pencils x0.27=40.5$
225 pens x 0.42=94.5$
Total 40.5$ + 94.50$=135 $
