Show how to write and evaluate an expression to represent and solve this problem: Jeff and his friend each text four classmates about a concert. Each classmate then texts four students from another school about the concert. If no one receives the message more than once, how many students from the other school receive a text about the concert?
THANK YOU!
To write and evaluate an expression for this problem, we can break it down into steps.
Step 1: Determine the total number of classmates Jeff and his friend texted.
Since Jeff and his friend each texted four classmates, the total number of classmates they texted would be 4 + 4 = 8.
Step 2: Calculate the total number of students from another school that each classmate texted.
Since each classmate texted four students from another school, we can multiply the number of classmates (8) by the number of students each classmate texted (4). This gives us 8 * 4 = 32 students from another school that were texted by the classmates.
Step 3: Calculate the total number of students from another school that receive a text about the concert.
Since no one receives the message more than once, it means that we don't have any duplications. Therefore, the total number of students from another school that receive a text about the concert would be the same as the total number of students texted by the classmates, which is 32.
So, the solution to the problem is that 32 students from the other school receive a text about the concert.
