A gallon of milks sells for $3.18 and a quart of milk sells for $0.76. Which item has the better unit price? Justify your answer

nataly862011 [7]

Answer:

$Second\ price\ that\ is\ 1\ quart\ milk=\$0.76\ has\ better\ unit\ price$

Step-by-step explanation:

Use gallon unit:

First Price:

$1\ gallon\ milk=\$3.18\\\\$

Second Price:

$4\ quart=1\ gallon\\\\1\ quart\milk=\$0.76\\\\4\ quart\ milk=4\times 0.76=\$3.04\\\\\Rightarrow 1\ gallon\ milk=\$3.04$

$1\ gallon\ at\ first\ price\ is\ greater\ than\ the\ rate\ of\ 1\ gallon\ at\ second\ price\\\\Hence\ 1\ quart=\$0.76\ has\ the\ better\ unit\ price.$

Second Method: Use Quart Unit:

First Price:

$1\ gallon=4\ quart\\\\1\ gallon\ milk=\$3.18\\\\4\ quart\ milk=\$3.18\\\\1\ quart\ milk=\frac{3.18}{4}=\$0.795$

Second Price:

$1\ quart\ milk=\$0.76$

$Second\ price\ that\ is\ 1\ quart\ milk=\$0.76\ has\ better\ unit\ price$

13x-7+7x-13=180 whats the answer?

Marianna [84]

Answer:

x=10

Step-by-step explanation:

13x-7+7x-13=180

Combine like terms

20x-20 = 180

Add 20 to each side

20x -20+20 = 180+20

20x=200

Divide by 20

20x/20 = 200/20

x = 10

Assuming they work until their cost become the same, obviously.

The difference between the first charge of painter A and painter B = 376 - 280 = 96.

The hourly cost difference between painter B and painter A = 15 - 12 = 3.

So, painter A in the first hour has 96 more dollars than painter B, and as every hour pass, the difference goes down by 3 (as painter B gets 3 more dollars every hour)

Therefore, it would take 96 : 3 = 32 hours for the cost to be the same

Recheck : After 32 hours, painter A has 376 + 32 x 12 = 760 (dollars)
painter B has : 280 + 15 x 32 = 760 (dollars)
