Lucy packs plates faster she packs 5 plates every minute. Mike packs 4 plates every minute because 3/4 of an hour is 45 minutes, then you divide 180 by 45 and the answer is 4 per minute. 
Franco would have to pack 90 plates every 20 minutes (1/3 of an hour) for his rate to be between Lucy's and Mike's. Lucy's rate is at 100 plates per 20 minutes because she can pack 5 plates every minute. Mike's it's at 80 plates per 20 minutes because he can pack 4 plates per minute. So that means that For Franco to be in the middle he has to pack 90 Plates every 20 minutes. 
Hope this helps!!!

To divide by a fraction, multiply by its reciprocal.

Lucy and Ethel’s favorite store was having a sale. Lucy bought 10 shirts and 4 pairs of jeans and spent $280. Sabrina bought 12
Sphinxa [80]

Answer:

Each shirt costs 12 dollars.

Each pair of pants cost 40 dollars.

Step-by-step explanation:

<u>Let x represent the shirts </u>

<u>Let y represent the pair of jeans</u>

10x + 4y = $280

12x + 5y = $344

<u>Use elimination method to eliminate y</u>

• Multiply the entire first equation by 5.

• Multiply the second entire equation by -4.

5(10x +4y = $280)

-4(12x + 5y = $344)

50x + 20y = 1400

-48x -20y = -1376

2x = 24

x = 12

Each shirt costs 12 dollars.

<u>Solve for how much each pair of jeans costs.</u>

10(12) + 4y = 280

120 + 4y = 280

4y = 160

y = 40
