Question 164584

Your BASIC EQN: {{{highlight(Y[x]=cost+2(x-1))}}}
Where:
{{{Y=Total_Charges}}}
{{{x=Number_of_Videos}}}
{{{cost=4.00}}}, basic cost per 1 video
Let's prove our BASIC EQN:
1 video=$4.00
{{{Y[1]=4.00+2(1-1)}}}
{{{Y[1]=4.00+0=4.00}}}, correct!
2 videos = $6.00
{{{Y[2]=4.00+2(2-1)=4.00+2(1)=4.00+2=6.00}}}, correct!
3 videos = $8.00
{{{Y[3]=4.00+2(3-1)=4.00+2(2)=4.00+4=8.00}}}. correct!
4 videos=$10.00
{{{Y[4]=4.00+2(4-1)=4.00+2(3)=4.00+6=10.00}}}, correct!
5 videos=$12.00
{{{Y[5]=4.00+2(5-1)=4.00+2(4)=4.00+8=12.00}}}, correct!
See the sequence, our eqn is good. Try the rest.
Now for 10 videos=$????, let's see:
{{{Y[10]=4.00+2(10-1)=4.00+2(9)=4.00+18}}}
{{{highlight(Y[10]=22.00)}}}
thank you,
