Step-by-step explanation:

4677 subscribers

Step-by-step explanation:

Here we are given that in 1985 the number of subscribers were 285. And there is growth of 75% per year from that year. let us calculate the no. of subscribers per year from there.

75% growth means 1.75 percent of previous figure. Let us see how . 75% of 1 = 0.75. Hence new value = 1+0.75=1.75. Hence  75% growth means 1.75 percent of previous figure

Y 1986 = 285*1.75 = 498.75

Y 1987 = 498.75 * 1.75 = 872.81

Y 1988 = 872.81 * 1.75 = 1527.42

Y 1989 = 1527 *1.75 = 2672.90

Y 1990 = 2672.90 * 1.75 = 4677.72

As the number can not be in decimals , we consider our answer to be 4677 subscribers.
