Rachel is typing a 1,500-word report. her progress is represented by the equation. 1,500 = 500 + 50t, where t is the number of minutes spent typing. if she does not take a break, how many minutes does. rachel need to type to finish her report?

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)

the answer is 62.8 cubic units
