Pedro went on vacation for 5 days his meals cost 10$ a day, his share of hotel cost 25.25$ a day, and the plane fare was 350$. What was the total cost of his trip?

i think it may be 526.25

Step-by-step explanation:

meal cost for the trip: 5x10=$50

Hotel cost for the trip: 5x25.25=$126.25

plane fare: $350

350+50=400

400+ 126.25=$525.25

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

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)
