Landon babysits and works part time at the water park over the summer. one week, he babysat for 3 hours and worked at the water park for 10 hours and made $109. the next week he babysat for 8 hours and worked at the water park for 12 hours and made $177. how much does landon make per hour at each job?

Landon earns $ 10.5 per hour for babysitting and $7.75 per hour at water park.

Step-by-step explanation:

Let b be the number of hours Landon babysits and w be number of hours Landon works at water park. Upon substituting our given values we can get a system of equations as:

We will use substitution property in order to solve this system of equations.

Now let us substitute w=7.75 in equation 1.

Therefore, Landon earns $10.5 for per hour babysitting and $7.75 for per hour at water park.

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)
