GREYUIT [131]3 years ago
5 0

Answer:

p=-7

Step-by-step explanation:

-11+10(p+10)=4-5(2p+11)

Firstly, expand the bracket

-11+10p+100=4-10p-55

Next, you collect like terms

10p+10p=4-55-100+11

20p=-140

Divide through by the coefficient of p

20p/20=-140/20

p=-7

tankabanditka [31]

Answer:

the total price of the CD including tax is $11.984

CD is 20% off

And, the sales tax rate is 7%

= $11.984

Hence, the total price of the CD including tax is $11.984
