Cremini:
$11.25 for 2/3 lb
2/3 lb = $11.25
1 lb = 11.25 ÷ 2/3 = $16.88 (nearest cent)
Chanterelle:
$7.99 for 1/2 lb
1/2 lb = $7.99
1 lb = $7.99 x 2 = $15.98

72 100
Cross multiply
45 times 100= 4500
72 times x= 72x
72x=4500
Divide
4500/72= 62.5%

Answer:
X=-0.9
Step-by-step explanation:
Subtract 1.1x on both sides
. 6x-1.1x=-0.5x
Then you have - 0.5x+1.2=1.65
Now subtract 1.2 on both sides
1.65-1.2=0.45
Now you have - 0.5x=0.45
Divide - 0.5x from both sides
0.45divided by - 0.5= - 0.9
