Answer:
this is correct
Step-by-step explanation:
f continous in x=30 means that it should be the same value for 1.25 x 30 and 1.10 x 30 + k so k =4.5
Fourth test mark should be 86
85 + 82 + 75 + 86 = 328
328 divide by 4 (as there are four tests) = 82
63/60min = 1.05k per min
(1.05k/min) * (20min) = 21k
