Step-by-step explanation:

step 1. (1) 5a +8c +4p = 57

(2) 9a +8c + 7p = 89

(3) 8a + 4c + 5p = 68.

step 2. this is a 3 variable system. solve the system.

step 3. eliminate c from (1) and (2) and also from (2) and (3). so you now have 4a + 3p = 32 and 7a + 3p = 47. now you have a two variable system

step 4. eliminate p by subtracting: 3a = 15 so a = 5.

step 5. if a = 5 then p = 4 ( plug into step 3)

step 6. if a = 5, p = 4, then c = 2 (plug into step 1).

step 7. apples = 5, pears = 4, cherries = 2.

<u>Complete Question</u>

The two-way table below gives the thousands of commuters in Massachusetts in 2015 by transportation method and one-way length of commute.

$\left|\begin{array}{c|c|c|c|c|c|c}$Transport Mode/Minutes&$Less than 15&15-29&30-44& 45-59&$60 or more &$Total\\---&---&---&---&---&---&---\\$Private vehicle & 636&908&590&257&256&2647\\$Public Transportation&9&54&96&62&108&329 \\$Other&115&70&23&7&7&222\\---&---&---&---&---&---&---\\$Total&760&1032&709&326&371 &3198 \end{array}\right|$

Answer:

$\dfrac{108}{329}$

Step-by-step explanation:

From the table above

Total Number of commuters who used public transportation=329

Number of commuters who spent 60 or more minutes on public transportation=108

Therefore:

Given that a commuter used public transportation, the probability that the commuter had a commute of 60 or more minutes:

P ( 60 + minutes ∣ public transportation ) = $\dfrac{108}{329}$
