Answer:

1.85

Step-by-step explanation:

So, s (sketchbook) is a+1.90.

8a+ 3(a+1.90)=26.05

8a+3a+5.7=26.05

11a=20.35

a=1.85

Check:

8x1.85=14.8

s=11.25

Answer:

A= 1.85

Step-by-step explanation:

8(a) + 3(a+1.90) = 26.05

distributed

8a+ 3a + 5.70 = 26.05

11a+ 5.70= 26.05

subtracted

11a= 20.35

divided

a= 1.85
