Decrease 64 g by 123%
please help i need a step by step explanation​

-14.72g

Step-by-step explanation:

64g represents a 100% value

To reduce it by 123% means 100%-123%=-23%

So calculate-23% of 64g

=-23/100×64g

=-14.72g

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
