Q. Melissa and Rachel like to make funny hats. Melissa has made

20

zebra-printed hats, and Rachel has made

h

striped hats. Together they have made a total of

42

hats.

\newline

Write an equation to describe this situation.

Define Variables: Let's denote the number of striped hats made by Rachel as $h$ . According to the problem, Melissa has made $20$ zebra-printed hats. Together, they have made a total of $42$ hats. We can express this relationship with an equation where the sum of the hats made by Melissa and Rachel equals $42$ .
Write Equation: Now, we write the equation using the information given. Melissa made $20$ hats, and Rachel made $h$ hats. The total number of hats made by both is $42$ . So, the equation is: $\newline$ $20 + h = 42$
Check Equation: We can check the equation by substituting a value for $h$ that would make the equation true. If Rachel made $22$ hats, then the equation would be: $\newline$ $20 + 22 = 42$ $\newline$ Which simplifies to: $\newline$ $42 = 42$ $\newline$ This is true, so our equation seems to be correct.
