The cost of a layer cake is $12.96 plus $3.55 per layer. if paul has only $30 to spend on a cake ,what is the most number of layers he can afford

4 layers with $2.84  left over

Step-by-step explanation:

You start off with the cost of the cake which is $12.96, then add $3.55 (in this case 4 times) until you get the closest number to $30 without going over ($27.16) . You find the amount of money that is left over by subtracting you original amount ($30) with the amount you spent total on the cake ($27.16) .

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
