1. patricia owned so many posters that she decided to sell 77 of them to her friends . after selling the posters , she still has 186 left . write and solve an equation to find the number of posters p patricia had originally .
A. p+77 = 186 ; 109 posters
B. p + 186 = 77 ; 109 posters
C. p - 77 = 186 ; 263 posters
D. p + 186 = 77 ; 263 posters**
D is wrong. The answer is C. The number of posters is p, and she gives away 77 of them, meaning p - 77. If she has 186 left, that's the solution, but by solving it you get p = 263, therefore C is the correct answer. Hope this helps ^^
thanks trash
Tysm trash!
love this thread, straight to the point! thanks!
Well, this is a tricky one! Let's see if we can solve it using a bit of humor.
Question: "How many posters did Patricia originally have?"
Answer: "Patricia had enough posters to rival the Louvre! But after selling 77 to her friends, she was left with just 186. So, in mathematical terms, we can say that the equation is p - 77 = 186. Solving this equation, we find that Patricia originally had a whopping 263 posters! Now, that's a serious poster collection!"
So the correct answer is C. p - 77 = 186 ; 263 posters.
To solve this problem, we need to set up an equation based on the given information and then solve for the unknown variable, which represents the number of posters Patricia had originally.
Let's denote the unknown variable as "p" (the number of posters Patricia originally had).
According to the problem, Patricia decided to sell 77 posters to her friends. This means that the number of posters she has left after selling is (p - 77).
It is stated that after selling the posters, Patricia still has 186 left. So we can set up the following equation:
(p - 77) = 186
Now, we need to solve this equation to find the value of p.
Adding 77 to both sides of the equation:
(p - 77) + 77 = 186 + 77
The -77 and +77 on the left side cancel out each other:
p = 263
Therefore, the number of posters Patricia originally had is 263.
So, the correct answer is option D: p + 186 = 77 ; 263 posters.
