3. The original price of the trampoline is $72

The marked off price is 72 times 70 percent.

72 x .70 = 50.4

The sales tax is 5%

50.4 + 50.4 x 0.05

50.4 + 2.52

52.92

He paid $52.92 in total.


4. A store bought a leaf blower for $48.50 and marked it up 100%

97 + 97 x 0.06

97 + 5.82

Answer:

The answer to your question is letter A. Regular size is cheaper than Economy size by $0.0003 per gram

Step-by-step explanation:

Cost of 1 gr of economy size

  5000 gr (5 kg) -------------------  $ 5.15

         1 gr            --------------------     X

x = 1 x 5.15 / 5000 = $0.0010

Cost of 1 gr of regular size

  820 gr -------------------   $0.60

       1 gr --------------------   x

x = 1 x 0.6 / 820 = $ 0.0007

Difference of cost  = $0.0010 - $0.0007 = $0.0003
