Colin wants to set up an aquarium.. He already has a tank, but needs to purchase fish, filters, and plants. If the cost of the fish is $84.79, the filters usually cost $60.45 but Colin finds them on sale for $44.75, and the cost of the plants is $18.66, determine how much of Colin’s $488.85 savings will be used to set up his aquarium.

y = i/2 xtnop + (3i/2 tnop+ 1)

step-by-step explanation:

the picture is the step by step explanation.

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

slope intercept form is y = mx + b

the circumference is c≈245.04
