Remark
You could use a formula to solve this
Cost per pound = Total Cost / # pounds
Problem One
Cost per pound = ?
Total Cost = 13.46
# pounds = 3.47
<u>Solution</u>
Cost per pound = 13.46/3.47 = 3.88 dollars / pound
Problem Two
Total Cost = 18.75
# pounds = 5.15
<u>Solution</u>
Cost per pound = 18.75 / 5.15 = 3.64 dollars / pound

after 28 s , it is 195 feet
rate of traveling
after 1.5 minutes, that is 90 s, diver must have traveled
Answer:
Isolate the variables in all cases. Note the equal sign, what you do to one side, you do to the other.
a) 3x = 18
Isolate the variable, x. Divide 3 from both sides:
(3x)/3 = (18)/3
x = 18/3
x = 6
b) 2x = 9
Isolate the variable, x. Divide 2 from both sides:
(2x)/2 = (9)/2
x = 9/2
x = 4.5
c) (x/5) = 7
Isolate the variable, x. Multiply 5 to both sides:
(x/5)(5) = (7)(5)
x = 7 * 5
x = 35
d) x/2 = 6.5
Isolate the variable, x. Multiply 2 to both sides:
(x/2)(2) = (6.5)(2)
x = 6.5 * 2
x = 13
