5+3x=4x
only when
x=5
The two expression are only equal at x=5
The answer is C. because 3(0.50) is $1.50 which equals the erasers price. then two notebooks are $5 each add up to $10. So 2(5). then last 6(0.75) is $4.5 which is the same as the price of six pencils.

Answer:
0.9265x
Step-by-step explanation:
x - 0.15x + 0.09(0.85x)
x is the initial amount, -0.15x is subtracting 15% of the original amount (leaving 0.85x), and 0.09(0.85x) is the 9% tax.
Simplified:
x - 0.15x + 0.09(0.85x)
= 0.85x + 0.0765x
= 0.9265x
The answer will be Y=6*5=30
