Find the percent change if the original is $300 and the new cost is $1,100?

The percentage change from $300 to $1,100 is 266.67% increase

How?

1,100 - 300 ÷ 300 = 2.6667

2.6667 x 100 = 266.67%

^this is how you find the percent in change

(You could have just asked me to show my work instead of reporting me- that was a bit uncalled for)

the correct answer is 828.07

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
