Mystery

100

At the candy store, Mr. Genteman bought four pounds of his favorite candy. If the candy is priced at $18 per five pounds, what did Mr. Genteman pay?

$18/5 = $3.60 per pound

$3.60 x 4 = $14.40

200

(7.54 x 10³) + (6.82 x 10³)

14.36 x 10³

= 1.436 x 10⁴

300

(x+4)/3 = (x+2)/4

x = -10

400

(3.8 x 10⁷)/(1.6 x 10³)

(3.6 x 10⁴)/1.6

= 23,750

= 2.375 x 10⁴
