For each babysitting job he takes on, Manuel charges $2 for bus fare plus an additional $6 for each hour he works at the job. On Saturday, Manuel earned $26 for one babysitting job.

If the question is how many hours he worked on Saturday, the answer is 4 hours.

Step-by-step explanation:

26-2=24

24/6=4

Beforehand, he already charges 2 dollars for each babysitting job. Subtract this from 26, leaving you with 24 dollars. Divide 24 by 6, with a sum of 4.

If he's worked 4 hours, he'd get 6 dollars per hour.

Quite simple? But in short, he worked 4 hours.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
