Sam is making Apple Pies and Pumpkin Pies for her pie shop. She sells each Apple Pie for $7 and each Pumpkin Pie for $6. If Sam sells a total of 80 pies one day and makes a total of $512, how many of each type of pie did she sell?

Write down the equations for the apple pie and pumpkin pie.

7A + 6P = 512

Step-by-step explanation:

A+P=80

P=80-A

7A+6(80-A)=512

7A+480-6A=512

A=32

80-32=48

Sam sold 32 apple pies and 48 pumpkin pies

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)
