Answer

$W = 5 + 0.64 * 50 = 37$

Work Step by Step

To use this model to predict the percentage of women lawyers in 2020, we need to: 1. Determine $x$, which is the number of years passed since 1970, which in 2020 is equal to: $2020-1970=50$ (years) 2. Substitute 50 for $x$, and use the formula to get the answer. $W = 5 + 0.64 * 50 = 5 + 32 = 37$
