I’ve fallen and i️ cant get up! (jk) i️ just really need on this algebra question? !

use cross products

(3r+6) *2 = 9*(2r-4)

6r+12 = 18r-36  distribute

12    = 12 r -36    subtract 6r from each side

48 = 12r  add 36 to each side

4=r  divide by 12

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

i do not know the answer
