Mindy conducted a survey of the phones in four stores and wrote the following observations:

5 of the 8 phones in store 1 were smartphones
13 of the 22 phones in store 2 were smartphones
22 of the 30 phones in store 3 were smartphones
12 of the 25 phones in store 4 were smartphones

based on the survey, which store had the greatest percentage of smart phones?

store 1
store 2
store 3
store 4

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
