Amilkshake vendor sells shakes in three different flavors: mango, strawberry, and chocolate. this table gives the number of shakes of each flavor sold during three shifts on one day. mango strawberry chocolate shift 1 16 13 29 shift 2 26 19 45 shift 3 6 11 0 total sales were $419 in the first shift, $649 in the second shift, and $96 in the third shift. if you form a linear system representing the data in the table and create a matrix from it, the determinant is 578. what is the price of one chocolate shake?

Step-by-step explanation:

you need to add together all the milkshakes sold and then add together the amount of money made and then divide the two numbers. i think this is right. hope i helped. i think your answer should be around 7 dollars for a milkshake.

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
