A meseum calculates the rate for groups by charging $4 per person along with a one-time $8 fee. If the cost for a group is $60,how many people are in the group?

13 persons

Step-by-step explanation:

The Museum Collects a One Time fee of $8 and $4 per person in the group.

Let the number of persons in the group=x

The total Cost for a group= $(8+4x)

If the cost for a group is $60, we want to determine x.

$(8+4x)=$60

8+4x=60

4x=60-8

4x=52

Divide both sides by 4

x=13

There are 13 persons in the group.

answer: ask

step-by-step explanation:

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)
