.45 + .09 = $.54
D - 180

1) D
10% of $0.45 is 0.045 (move the decimal to the left one space). Double that values gives 9 cents- the amount the store must increase the price of the lettuce by. $0.45+.09 = $0.54
2)D
10% of 150 people is 15 people. So 20% would be 30. The answer is therefore 150+30 = 180.

1) $0.45 + 20%
= $0.45 * 120/100
= $0.54
(answer D)
2) 150 * 120%
= 150 * 120/100
= 180
(answer D)
