How many pounds of chocolate worth $1.5 a pound must be mixed with 10 pounds of chocolate worth 60 cents a pound to produce a mixture worth $1 a pound?

answer asap

Your rows would be $0.90 Chocolate, $1.20 Chocolate, and the Total Chocolate Mix, and your columns would be the Amount of Chocolate in #s and the Total Costs

(This is the best I can do coming up with a grid)

amt (#)total costs

$0.90109.00

$1.20x1.20x

Total Mix10+x9+1.2x

Using this grid, you see that 10+x=9+1.2x so solve for x

10+x -x=9+1.2x -x

10=9+.2x

10 -9=9+.2x -9

1=.2x

1/.2=(.2x)/.2

x=5, so you need 5lbs of the $1.20 chocolate to produce a mixture worth $1.00

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
