store b. 10% off sale
store c. 5% off sale plus store pays sale tax
store d. "no tax" sale

Store B has the best deal .

Step-by-step explanation:

Walden's family is shopping for a reclining chair.

At four stores the price of the chair is $800 plus 5% sales tax. =

800 + (5% × 80)  =  800 + ( 0.05 × 80)

= 800 + 40 = $840

Each store is offering a different promotion.

Store A. $75.00 instant rebate

The price will be = 840.00 - 75.00 =  $765.00

Store B. 10% off sale

The price will be  =  840 - (10% × 840)

                             = 840 - 84 = $756.00

Store C. 5% off sale plus store pays sale tax.

The price will be = 840 -  40 - (5% × 800)

                           = 800 - 40 = $760

Store D. "no tax" sale

The price will be = 840 - 40 = $800

Price on all stores :

Store A : $765

Store B : $756

Store C : $760

Store D : $800

So Store B has the best deal .

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
