Final answer:
The equation to find the number of pairs of mittens sold by Jaheem to make a $125 profit would normally be 'price per mitten x m = 125'. However, none of the provided options match the correct equation needed for solving Jaheem's problem.
Step-by-step explanation:
The equation to determine the number of pairs of mittens Jaheem must sell to make a profit of $125 can be set by assuming m stands for the number of mittens sold. Let's also assume he earns a certain amount per mitten sold, which we'll call price per mitten. If we multiply the number of mittens sold (m) by the price per mitten, we should get his total earnings.
To make a profit of $125, the equation would be price per mitten × m = 125. However, none of the options given (a, b, c, d) reflect this equation. Each proposed option is missing an essential part of the problem: the price per mitten. With the provided options, we can't choose a correct one without this piece of information.
