Question

Jada has challenged herself to do at least 100 full push-ups this week. On Sunday, she does 30 push-ups. Her arms are sore, so she decides to do fewer push-ups on the remaining days of the week. She wants to do the same number of push-ups each day for the rest of the week. Write and solve an inequality for the number of push-ups Jada needs to do each day for the rest of the week to meet her goal of 100 push-ups. Which answer choice best interprets the solution in the context of the problem?(1 point)

To find out how many push-ups Jada needs to do each day for the rest of the week, we can set up an inequality.

  1. Total Push-ups Goal: Jada wants to do at least 100 push-ups in total this week.
  2. Push-ups Already Done: She has done 30 push-ups on Sunday.

Let \( x \) be the number of push-ups she will do each day for the remaining days of the week. There are 6 days left in the week (Monday to Saturday).

The inequality can be set up as follows:

\[ 30 + 6x \geq 100 \]

Now, we will solve the inequality:

  1. Subtract 30 from both sides:

\[ 6x \geq 100 - 30 \] \[ 6x \geq 70 \]

  1. Divide both sides by 6:

\[ x \geq \frac{70}{6} \] \[ x \geq \frac{35}{3} \approx 11.67 \]

Since Jada is doing whole push-ups, we round up to the nearest whole number, giving us:

\[ x \geq 12 \]

Now, let's interpret the solution in the context of the problem. Jada needs to do at least 12 push-ups each day for the rest of the week to meet her goal of 100 push-ups.

The correct answer choice is:

  • Jada needs to do at least 12 push-ups each day for the rest of the week to meet her goal.
