Martha works in a toy shop and earns $44 per day. She earns an extra $2 for each toy she sells. If Martha wants to earn at least $80 per day, which inequality shows the minimum number of toys, n, that she should sell?

1) 44 + 2n ≥ 80, so n ≥ 18

2) 44 + 2n ≤ 80, so n ≤ 18

3) 44 + 2n ≥ 80, so n ≥ 34

4) 44 + 2n ≤ 80, so n ≤ 34

Answer:

The answer is 1) :)

Step-by-step explanation:

Answer:

N.2

Step-by-step explanation:

Because if it's the minimum it can't be 34.

So it's either 1 or 2.

N.1: 44+2(19) ≥ 80, 44+38 ≥ 80, 82 ≥ 80

N.2: 44+2(18) ≤ 80, 44+36 ≤ 80, 80 ≤ 80

The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of students in seventh and eighth grade combined is 584; 5/8 of them are seventh graders and 3/8 of them are eighth graders. If 4/5 of the seventh graders participated in track-and-field day and 7/8 of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.

Read the excerpts from Team Moon and the NASA article.

And only now—a solid, panic-stricken, gut-wrenching, heart-palpitating ten minutes by clock but feeling like an eternity later—did it sink in for John Coursen, Tom Kelly, and a lot of the other Grumman folks who had poured years of their lives into building the lunar module: Their baby was on the moon. Let the cheering begin!

When the lunar module lands at 4:18 p.m. EDT, only 30 seconds of fuel remain. Armstrong radios "Houston, Tranquility Base here. The Eagle has landed." Mission control erupts in celebration as the tension breaks, and a controller tells the crew "You got a bunch of guys about to turn blue, we're breathing again."

How is the information in the excerpts different?

A. The first excerpt is less emotional than the second excerpt.
B. The first excerpt is less interesting than the second excerpt.
C. The first excerpt is more emotional than the second excerpt.
D. The first excerpt is more interesting than the second excerpt.
