P/9 = 90
Multiply 9 to 90 to isolate the variable.
P = 9 x 90
P = 810
Yes, the distance a sailfish swims propotional to the number of hours it swims
Answer:
Step-by-step explanation:
22.75/6 boxes is $3.79 per box
30/8 boxes is $3.75 a box
38/10 boxes is $3.80 a box
68/18=3.70 a box if you combine the last two.
So no, the 6 boxes at $3.79 a box is not a better buy.
