Claire has received scores of 85,88,87,and 85 on her algebra tests. what is the minimum score she must receive on the fifth test to have an overall test score average of at least 88?

88*5 = 440

 so all 5 tests need to equal at least 440

85 +88 +87 +85 = 345

440-345 = 95

 she needs at least a 95 to have an 88 average

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

(23*2)-12=x     x=34
