Answer:
a) 5,000 b) 3,600
Step-by-step explanation:
a) there are four different slots, and for the first three slots there are a possibility for 10 different numbers and in the last slot there can only be 5 different numbers. So you get 10 x 10 x 10 x 5 which leaves you with 5,000 possibilities
b) the same thing as above but know you have fewer numbers 10 x 9 x 8 x5 which gives you 3,600 possibilities
C. The discounted price of the shorts.
Say the discount is 30%, that translates to 0.30 as a decimal. Then (1-x) would be (1-0.30). That leaves 0.70 left as the new price being paid for with the discount included.
First Divide both sides by -5.73
-5.73q/-5.73=97.41/-5.73
Answer: q=-17
