En una plantación especializada en productos orgánicos, un técnico agrícola
tiene dos fertilizantes que contienen
diferentes concentraciones de nitrógeno,
uno tiene 3% y el otro tiene 11%. ¿Cuántas
libras de cada fertilizante debe mezclar para
obtener 20 libras con una concentración de
9%?

i'm sure goog can you get that answer

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

114 plus 113 times 2 and 114 times 3

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
