15(30) = 100x

450 = 100x

450/100 = x = 4.5 tablespoons per 30 tablespoons

second answer

26)

0.40x = 360

x = 360/0.40 = 900

fourth choice

11)

12% annual is roughly 1% monthly

1% = 0.01

0.01(500) = $5

$100/$5 = 20 months

13)

x(1.15) = 40,000

x = 40,000/1.15 = $34,782.61

40,000(0.85) = $34,000

0.85x = 40,000

x = 40,000/0.85 = $47,058.82

40,000(0.15) = $6000

The third choice is the highest amount.
