to get an A, she needs >=160 points and she already has 125 points

let 'x' be the number of points on the last part of her project then

125 + x >= 160

x >= 160 - 125

x >= 35

Sarah needs at least 35 points on the last part of her project.

Answer:

P ≥ 35

Step-by-step explanation:

Naming P to the Points needed for the last part of Sarah's project,

we can define an inequation modelling in which cases Sarah will have enough points for an A or better:

It is stated that:

  • An A is achieved with 160 points.
  • Sarah already has been given 125 points.

Then the inequation can be written:

[Points-so-far] + [Points-needed] greater or equal than 160

<u>In math symbols:</u>

125+P\geq 160\\P\geq 160-125\\P\geq 35
