If this ratio is proportional to the ratio of students in the school and the number of boys in the school, which of the following proportions could be used to find the number of students in the school? It is given that there are 468 boys in the school. Select one that applies. 7th grade

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

ratio is 2 : 9

the answer is three

13.5 : 3
