Alex and his 4 friends went to go get pizza. alex paid for half of the pizza and his friends paid for the rest. if the bill was 30,00, how much did each friend pay?

Alex paid for half. That means he paid 15,000. Which seems like a ridiculously expensive pizza. That leaves 15,000 which we divide by 4, to find what his four friends paid. Each friend paid 3,750. Hope that helps! Mark Brainliest if it does. Thank you!

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)

x=6 and x=3
