Jerrell made $24 babysitting his cousins on Saturday night. This is $7 more than he made babysitting Friday night. How much money did Jerrell make babysitting on Friday night? Write and solve an equation to find the answer.
Let's say Jerrell made x dollars babysitting on Friday night.
Since he made $7 more babysitting on Saturday night, he made x + $7 babysitting on Saturday night.
We know that Jerrell made $24 babysitting on Saturday night, so we can set up the equation x + $7 = $24.
Subtracting $7 from both sides of the equation, we get x = $24 - $7 = $<<24-7=17>>17.
Therefore, Jerrell made $17 babysitting on Friday night. Answer: \boxed{17}.
