(1) Yesterday, the store sold 20 pieces of the M1 model.
(2) A quarter of the cellular phones sold yesterday were M1 models sold together with the P2 program.

This is a table problem, I have a labelled table shown below where our goal is to find the total.
Statement 1:
There were 20 M1 models and 8 M2 models sold, so 28 cell phones in total. Sufficient.
Statement 2:
We can find the total x with the equation \(13 + \frac{1}{4}x + 8 = x\). Sufficient.
Ans: D

My vote goes to D

Every cellular phone is sold together with one of the two telecommunication programs. Yesterday, the store sold 8 pieces of the M2 model. In addition it sold 13 pieces of the M1 model together with the P1 program. How many cellular phones (of both brands) did the store sell yesterday?
M2(All) = 8, M1(P1) = 13, Need: M1(P2) = ?
Models other than M1 with P2 = 21
(1) Yesterday, the store sold 20 pieces of the M1 model.
M1(All) = 20, Total = 20+8=28
Keep A and D
(2) A quarter of the cellular phones sold yesterday were M1 models sold together with the P2 program.
So, 75% of phones sold were models other than M1 with P2.
let x be Total
3/4*x = 21
x =28
Both Satisfies. Pick D.
