Let's solve the expression step by step:
-
Start with the expression:
\( 2(1.60 + 7) - 4.90 \) -
Calculate the value inside the parentheses:
\( 1.60 + 7 = 8.60 \) -
Substitute that back into the expression:
\( 2(8.60) - 4.90 \) -
Multiply:
\( 2 \times 8.60 = 17.20 \) -
Now substitute that back in:
\( 17.20 - 4.90 \) -
Finally, subtract:
\( 17.20 - 4.90 = 12.30 \)
So, the final result is:
\( \boxed{12.30} \)
