George found that he blinked 85 times in 15 minutes. At this rate, how many seconds passed during 51 blinks?

1 answer:

6 0

First convert the 15 minutes to seconds
60 sec-= 1 minute
900 sec = 15 minutes

ratio and proportion

85 blinks/900 sec= 51 blinks/ x seconds

cross multiply
85x=45900
divide by 85
x= 540 seconds
hope this helps

A video game that costs $30 is on sale for 25% off. What is the sale price?

If it is on sane for 25% off, that's the same as being on sale for 75% of the original price.

Multiply the original cost by 75% in decimal form.

30*.75=22.5
Final answer: $22.50
