#### Answer

$10≤C≤35$

#### Work Step by Step

The interval on the Celsius scale corresponds to the temperature range$50≤F≤95$ can be calculated as follows: Given: $50≤F≤95$ $50-32≤F-32≤95-32$ $18≤F-32≤63$ $\frac{5}{9}(18)≤ \frac{5}{9}(F-32)≤\frac{5}{9}(63)$ $10≤ \frac{5}{9}(F-32)≤35$ $10≤C≤35$ Therefore, the interval on the Celsius scale corresponds to the temperature range$50≤F≤95$ is $10≤C≤35$.
