Answer 1

To evaluate the expression \(2.4x + 6.2y\) for \(x = 3.5\) and \(y = 1.8\), we substitute the values of \(x\) and \(y\) into the expression:

\[
2.4(3.5) + 6.2(1.8)
\]

Calculating \(2.4 \times 3.5\):

\[
2.4 \times 3.5 = 8.4
\]

Now calculating \(6.2 \times 1.8\):

\[
6.2 \times 1.8 = 11.16
\]

Now add the two results together:

\[
8.4 + 11.16 = 19.56
\]

Thus, the value of the expression \(2.4x + 6.2y\) for \(x=3.5\) and \(y=1.8\) is:

\[
\boxed{19.56}
\]

So the correct response is **19.56**.
