Answer:
You would get 50 coins in that time.
Step-by-step explanation:
To find this, we first need to find the unit rate. We can get that by dividing the amount of coins by the amount of time.
15 coins/ 30 mins = .5 coins per minute.
Now, we have 100 minutes in the second part of the problem, so we multiply the rate by that amount of time.
.5 coins per min * 100 mins = 50 coins
We can use the is/of = p/100 method here. Our given values are 90% and 1000. Think: "What number is 90% of 1000?" Let's plug in our values.
x/1000 = 90/100
Solve for x.
x = (1000)(0.9)
x = 900
So, 900 is 90% of 1000.
