Apost office charges 50k for a telegram of 15 words or less it charges an extra 3k for every word above 15 words find the cost of 30 words telegram

95k

Step-by-step explanation:

It costs 50k for the first 15 words, and then 3k for every additional word. So you multiply 3 * 15 = 45 and then add the original 50 so 50+45=95

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
