Question

charlotte had 90 posters to hang up around the school. she gave 14 posters to each of 3 students. then she took the remaining posters and divided them up equally between the 3 students. 90 is represented as three sections of x + 14. there is a blank box below and a calculator interface with numbers and operations.

Explanation:

Step1: Calculate total given posters

Total posters given = $14 \times 3 = 42$

Step2: Find remaining posters

Remaining posters = $90 - 42 = 48$

Step3: Set up equation for equal split

Each student gets $x$ more, so:
$$3(x + 14) = 90$$
Simplify: $x + 14 = \frac{90}{3} = 30$

Step4: Solve for $x$

$x = 30 - 14 = 16$

Answer:

$x = 16$
(The remaining 48 posters are split equally as 16 per student, so the missing equation to represent the total is $3(x + 14) = 90$, and the value of $x$ is 16)
