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:
I made an equasion
8(a) + 3(a+1.90) = 26.05
distributed
8a+ 3a + 5.70 = 26.05
Added
11a+ 5.70= 26.05
subtracted
11a= 20.35
divided
a= 1.85
