Solve the equation from the previous problem: "The boardwalk has two bike rental shops. Ray’s Rentals charges a rate of $14.00 plus $9.00 an hour to rent a bike. Bentley’s Bikes charges a rate of $18 plus $7 an hour to rent a bike. For what number of hours would the companies charge the same?

The second hour!

Step-by-step explanation:

14+9= 23+9=32+9=41+9=50+=59

18+7=25+7=32

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
