Substituting x=3 in the equation, we get:
y = 0.1(11ea7dab_3904_15d9_b67a_ef9427a1d260_TB3448_11_TB3448_11) + 2.1(3) + 8
y = 11ea7dab_3904_15d9_b67a_ef9427a1d260_TB3448_11_TB3448_11 + 6.3 + 8
y = 11ea7dab_3904_15d9_b67a_ef9427a1d260_TB3448_11_TB3448_11 + 14.3
Rounding to two decimal places, we get y ≈ 15.2. Therefore, the correct option is D.
