A retail shop accepts only cash or checks. Suppose that 57% of its customers carry cash, 50% carry checks, and 39% carry both cash and checks. What is the
probability that a randomly chosen customer at the shop is carrying cash or checks (or both)?
Write your answer as a decimal (not as a percentage).

A retail shop accepts only cash or checks. Suppose that

46

% of its customers carry cash,

37

% carry checks, and

74

% carry cash or checks (or both). What is the probability that a randomly chosen customer at the shop is carrying both cash and checks?

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!
