Four students are going on a trip. Each student needs at least $2000 for the trip. each student writes an inequality that can be used to determine the number of weeks,x, that the student will need to save up the money for the trip. The inequalities are shown in the table below.

Lin 50x+ 1400
`\geq`2000
Reza 250x+ 1000
`\geq`2000
Pierre 10x+1200
`\geq`2000
150x+200
`\geq`2000

`\geq`12
a. lin
b. reza
c. pierre
d. hermione

Answer 1
