The drama club spent $608 on food for a party for its 38 members. The hall they rented costs $50 per hour. The door prize was worth $200. Let -A- be the amount spent on food per person and let -B- be the number of hours they rented the hall. Which equation represents how much was spent on this event? Let S be the total amount spent.
S = 608
S = 200 + 608 ÷ 38 + 50b
S = 200 + 38a + 50b
S = 608 + 38a + 50b

The answer is number 3!

3rd option

Step-by-step explanation:

the image of (6, 9) under a dilation is (4, 6). the scale factor is

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)
