If 50% of a number is 150 and 30% of the same number is 90, find 80% of that number.

240

Step-by-step explanation:

We know that 50% of the number is 150 so we can assume the number is 300(if its 50% just double that number). Next we use the equation 0.80 x 300 which gives us the answer 240.

240

Step-by-step explanation:

50%*x=150

0.5x=150

x= 300

30%*x=90

0.3x= 90

x= 300

80%*300=

0.8*300= 240
