Question 607662
This equations can be signified as:
{{{tn=100+25(n-1)}}}
n=tens of feet
tn=cost to build that ten feet
ex. to build 10 feet plug in 1 for n
{{{t1=100+25(1-1)}}}
{{{t1=100}}}
keep going
{{{t2=100+25(2-1)}}}
{{{t2=125}}}
{{{t3=100+25(3-1)}}}
{{{t3=150}}}
{{{t4=100+25(4-1)}}}
{{{t4=175}}}
{{{t5=100+25(5-1)}}}
{{{t5=200}}}
{{{t6=100+25(6-1)}}}
{{{t6=225}}}
{{{t7=100+25(7-1)}}}
{{{t7=250}}}
{{{t8=100+25(8-1)}}}
{{{t8=275}}}
{{{t9=100+25(9-1)}}}
{{{t9=300}}}
Then add all the tn's together
{{{100+125+150+175+200+225+250+275+300=1800}}}
Thus it will take $1800 to build the tower
