Step-by-step explanation:

Cole and Jamie are raising money for the annual Walk for Hunger in their city. They each have a goal to raise $250. So far, Cole has raised $150 and Jamie has raised $180.

What percent of their goal did each boy raise so far?

a) Percent of Cole's goal

= Amount raised by Cole/ Total amount × 100

= $150/$250 × 100

= 60%

b) Percent of Jamie's goal

Amount raised by Jamie / Total amount × 100

= $180/$250 × 100

= 72%

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)
