It is given that:

Carrie couldn't find a recipe that would make four servings. She decided to use a recipe for eight servings and use only half as much of each ingredient.

i.e. she is using half  actual amount which is given for the 8 servings.

Now, it is given that:

The recipe for eight called for one and a fourth cups of raisins.

i.e. the cup of raisins used for eight servings is:

i.e.

Hence, the number of cups of raisins she used for 4 people 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)
