An advertisement claims that a 5-pound box of detergent will wash 20 loads of a laundry. a 5-pound box costs $3.50. a 15-pound box costs $10.00. about how much will you save per load if you buy the 15-pound box?

You save $0.008  per load if you buy the 15-pound box.

Step-by-step explanation:

IN 5 POUND BOX

Here, 5 pound box can wash 20 loads

Also, 5 pound box costs $3.50

⇒ The cost of doing 20 loads  = $3.50

⇒ The cost of 1 load  =

So, the cost of laundering 1 load here  =  $0.175

IN 15 POUND BOX

Here, 15 ( = 5 x 3)  pound box can wash 20 x 3  = 60  loads

Also, 15 pound box costs $10.00

⇒ The cost of doing 60 loads  = $10.00

⇒ The cost of 1 load  =

So, the cost of laundering 1 load here  =  $0.167

Now, Savings  = Cost per load in 5 pound box - Cost of 1 load in 15 pound

= $0.175  - $0.167

= $0.008

Hence, you save $0.008  per load if you buy the 15-pound box.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
