Betty and ben had 200 computer problems last month. tim, the mechanic, was called by betty 12 times and by ben 28 times to solve the problem. find the percent that ben called tim, and find the percent that betty called tim.

Ben called Tim 14% and Betty called Tim 6%.

Step-by-step explanation:

Given:

Betty and ben had 200 computer problems last month.

Tim, the mechanic, was called by Betty 12 times and by ben 28 times to solve the problem.

Now, to find the percent that Ben called Tim, and Betty called Tim.

So, percent Ben called Tim:

Percent Ben called = 14.

Now, the percent Betty called Tim:

Percent Betty called Tim = 6.

Therefore, Ben called Tim 14% and  Betty called Tim 6%.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
