A $45.00 mixer sold for $47.70 with tax. What is the percent of the sales tax ?

6%

Step-by-step explanation:

You can start off by subtracted $47.70 by $45.00. You will get $2.70. You then will do $2.70 divided by $45.00.

2.7 / 45 = 0.06

there is no question content here, but you for the free points! : d

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
