5. Carlos has noticed that because each of his purchases have been somewhat similar, it has
been easy to figure out the cost of each item.
However, his last set of receipts has him puzzled.
One week he tried out cheaper brands of cat and dog
food.
On Monday he purchased 3 small bags of cat food and
5 small bags of dog food for $22.75.
Because he went through the small bags quite quickly.
he had to return to the store on Thursday to buy 2 more
small bags of cat food and 3 more small bags of dog
food, which cost him $14.25.
Based on this information, figure out the price of each
bag of the cheaper cat and dog food.

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
