Question

10. Marcelle uses a total of 6 plates to add 110

pounds to a weight lifting bar. He uses 25-
pound plates and 5-pound plates. Write and
solve a system of equations to find the
number of 25-pound plates and the number
of 5-pound plates he uses.

Answer 1

Marcelle will use 4 plates of the 25 lb & 2 plates of the 5 lb to fabricate the 110 lb weight lifting bar.

Explanation:

There are 6 plates which consist of 25 lb plates and 5 lb plates.

We need to figure out how many of each one compose 110 lb.

Thus, 25 x 4 = 100... 4 plates of 25 pounds.

5 x 2 = 10 ... 2 plates of 5 lbs.

100+10= 110, which is our goal! And a total of 6 plates were used!

All things put into great consideration, Marcelle will use 4 plates of the 25 lb & 2 plates of the 5 lb to fabricate the 110 lb weight lifting bar.

I hope this helped!
