We need to solve the formula for t . i=prt i=$75 p=$500 r=5%
what is i

3 years

Step-by-step explanation:

Use the formula for simple interest:

replace each parameter with the given values (remember that the rarte "r" needs to be included in its decimal form 5%=0.05), and solve for the unknown t:

The answer for the time comes in years, therefore t is 3 years

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'.
