If 3 p + 3 4 = 90

3p+34=90

, 2 r + 44=76

2r+44=76

, and 5 3 + 6 s = 1421

53+6s=1421

, what is the product of p

p

, r

r

, and s

s

?

3p + 34 = 90

3p = 90 - 34

3p = 56

p = 56/3

p = 18.67 (thats rounded)

2r + 44 = 76

2r = 76 - 44

2r = 32

r = 32/2

r = 16

53 + 6s = 1421

6s = 1421 - 53

6s = 1368

s = 1368/6

s = 228

" the product " means multiply

p x r x s = 18.67 x 16 x 228 = 68,108.16
