Equation:______
They sold_____ subscriptions in all.
Charlene, Mark, and Paul sold a combined total of 44 magazine subscriptions for their fundraiser.
In this problem, Charlene, Mark, and Paul collectively sold magazine subscriptions. We need to find the total number of subscriptions sold. We can do this using simple addition: Charlene sold 15 subscriptions, Mark sold 17 subscriptions, and Paul sold 12 subscriptions. Therefore, using s to represent total subscriptions, our equation would be: s = 15 (Charlene's sales) + 17 (Mark's sales) + 12 (Paul's sales). Summing the numbers, s = 44. Hence, they sold 44 subscriptions in total.

An automated car wash can wash 120 carsin 20 hours.
In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is that an automated car wash can wash 30 cars in 5 hours.
Now, an automated car wash can wash 30 cars in 5 hours.
Then, 1 car can be washed in (5/30) hours.
So, 120 cars will take (5/30 x 120) hours
(5/30 x 120)
5 x 4
20 hours
Therefore, an automated car wash can wash 120 carsin 20 hours.
