Professor Stache awarded 500 certificates, some for math, and some for science. Girls won 2/3 of the math certificates and 1/2 o

wariber [46]

Answer:

200

Step-by-step explanation:

<u>Given:</u>

Total certificates = 500
Math = m
Science = s

<u>Equations </u>

m+s = 500 ⇒ s = 500 - m

<u>Girls who won certificates:</u>

2/3m = 50 + 3/2*1/2s
2/3m = 50 + 3/4s

<u>Multiply both sides by 12 to clear fractions</u>

8m = 600 + 9s

<u>Substitute s</u>

8m = 600 + 9(500 - m)
8m = 600 + 4500 - 9m
17m = 5100
m = 5100/17
m =300

<u>Girls who won math:</u>

2/3*300 = 200
