Answer:
t = 115
s = 60
g(x) = 10/23x - 10
Step-by-step explanation:
find s first since its easy (it goes up by 10's)
then take a pair from the table that corresponds such as 69 for x and 30 for g(x) and turn them into a fraction:
69/30
do the same for t:
t/50
equal 69/30 to t/50 and solve using cross multiplication:
69/30 = t/50 =
30t = 3450
/30 /30
t = 115
honestly had a little hard time finding the equation but basically I simplified the fraction 30/69 to get 10/23 for slope and then I insert a corresponding x and y value into y= mx+b with the slope value to find b.

Answer:
342.85714 %
Step-by-step explanation:
Percentage increase is given by
increase= (new - original)/ original * 100 %
The new is 186 and the original is 42
= (186 - 42)/ 42 * 100 %
=144/42* 100 %
=3.42857 * 100%
=342.85714 %
