at an assembly 7 out of the first 10 students who entered the gym were carrying the backpack. Based on the information, if 700 students were at the assembly, how many students to be expected to be carrying a backpack?

i dont know :/ im sorry and my mind is not on the mood for work sadly

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

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
