Solve the Expression: 8(x-7)+4(6-2y) with x=7.1 and y=5/8

To solve the problem, we need to substitute the given values into the expression and simplify:

• Step 1: Substitute $x = 7.1$ into the expression $8(x-7)$.
  This gives us $8(7.1-7) = 8(0.1) = 0.8$.
• Step 2: Substitute $y = \frac{5}{8}$ into the expression $4(6-2y)$.
  First, calculate $2y = 2 \times \frac{5}{8} = \frac{10}{8} = 1.25$.
  Then, $6 - 1.25 = 4.75$.
  Finally, $4(4.75) = 19$.
• Step 3: Add the results from Step 1 and Step 2.
  That is $0.8 + 19 = 19.8$.

Therefore, the result of the expression $8(x-7) + 4(6-2y)$ with $x = 7.1$ and $y = \frac{5}{8}$ is $\mathbf{19.8}$.
