If the commuter wants to buy 20 weeks of tickets, how much must he add to his account?

doing this so i can get rid of my points

$55

Step-by-step explanation:

Start with $245.

Calculate to total money the commuter needs to buys 20 weeks of tickets.

Multiply the number of weeks by the price per week.

20 X $15 = $300

He will need $300 for 20 weeks of tickets.

Subtract what he has from the amount he needs.

$300 - $245 = $55

Therefore the commuter will need to add $55 to the account to afford tickets for 20 weeks.

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.

exactly you go it
