Question

Ichiro Suzuki’s batting average in 2001 was .350. The all-time American League leading hitter was George Sisler of St. Louis in 1922. Write and solve an equation to find Sisler’s batting average that year, given that his average x was .070 more than Ichiro Suzuki’s average in 2001.

Answer 1

For this case, the first thing we must do is define a variable.
We have then:
x: George Sisler's average
y: Suzuki's average
We then have the following equation that models the problem:

`x = 0.070 + y`
Substituting values we have:

`x = 0.070 + 0.350 x = 0.420`
Answer:
Sisler's batting average that year was:
x = 0.420
