At the grocery store. Martin uses some coupons and saves $5.75 off his total bill. His new bill comes to $21.36. What was the amount of Martin’s bill before using the coupons? Define your variable and what it represents. Write and solve an equation to find the amount of Martin’s bill before using the coupons. NO “x =” EQUATIONS!!

$27.11

Step-by-step explanation: $5.75 + $21.36= $5.75

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
