You compare prices of limousines for the spring dance. company a charges a $250 fee plus $130 for each hour you use the limo. for a similar limo, company b charges a $125 fee plus $155 for each hour. after how many hours of use will company b cost more than company a?

5 hours

Step-by-step explanation:

Let h be the amount of hours that the limo is hired, we must determine the hours of use will company B cost more than company A. We have an inequality expression in terms of total cost for company A and B:

On the left side we have company A total cost and on the right side we have company B total price:

We can solve for h:

After 5 hours company B will cost more than company A

your answer is b ^w^ hope i

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)
