Answer:
a. $0.47 per ounce
b. $0.36 per ounce
c. the gallon size costs less per ounce
Step-by-step explanation:
A unit rate is a rate that is expressed with one unit in the denominator. That is, it is <some amount> per unit. The <some amount> value will generally depend on what unit is chosen. This problem suggests the desired unit is 1 oz of paint.
__
<h3>a.</h3>
Unit cost for a quart:
ratio = cost/ounces = $14.99/(32 oz) ≈ $0.468/oz ≈ $0.47/oz
__
<h3>b.</h3>
Unit cost for a gallon:
ratio = cost/ounces = $45.99/(120 oz) ≈ $0.359/oz ≈ $0.36/oz
__
<h3>c.</h3>
The cost per ounce is less for the gallon size. If at least 3 quarts of paint is needed, then buying it in the gallon size will cost less.
If less than 3 quarts are needed, then a gallon container will cost more than is necessary for the paint required. The "better deal" depends on the amount of paint required.

"B" is the answer.

Part A is accomplished by first factoring out the b^2 to get
. Factor that completely using the quadratic formula to get
. Part B is done entirely with the quadratic formula (only cuz that's the easiest way to factor a second degree polynomial!) to get (x-9)(x-9) or (x-9) multiplicity 2. Part C is done by taking roots. Keep in mind that since this is a second degree polynomial you will have 2 solutions.
, therefore,
and
which is +11 and -11. And you're done! Factoring is very important...make sure you learn it and learn it well!!!
Answer:
The flea treatment is $2.05 cheaper at Pet Store 1.
Step-by-step explanation:
Pet store 1
Regular price = $33
40% off the regular price
= 40% of $33
= 0.4 × 33
= $13.2
25% off the regular price
= 25% of $33
= 0.25 × 33
= $8.25
Total paid = $33 - $13.2 - $8.25
= $11.55
Pet store 2
Regular price = $34
55% off of the regular price
= 55% of $34
= 0.55 × 34
= $18.7
5% off of the regular price
= 5% of $34
= 0.05 × 34
= $1.7
Total paid = $34 - $18.7 - $1.7
= $13.6
Difference in price = $13.6 - $11.55
= $2.05
The flea treatment is $2.05 cheaper at Pet Store 1.
