48 corn seeds sprouted. This was 75% of the seeds that were planted. How many of the plants did not sprout?
Let's start by using algebra. Let's call the total number of seeds that were planted "x". We know that 75% of these seeds sprouted, or in other words, 0.75x sprouted. We also know that the number of sprouted seeds is 48. So we can set up an equation:
0.75x = 48
Now we can solve for x:
x = 48 ÷ 0.75
x = 64
So there were 64 seeds planted in total. We can use this information to calculate how many seeds did not sprout:
Number of seeds that did not sprout = Total number of seeds - Number of seeds that sprouted
Number of seeds that did not sprout = 64 - 48
Number of seeds that did not sprout = 16
So 16 of the seeds did not sprout.
The sale price of $24 was 60% of the regular price. What was the regular price?
Let's start by using algebra. Let's call the regular price "x". We know that the sale price was 60% of the regular price, or in other words, 0.6x. We also know that the sale price was $24. So we can set up an equation:
0.6x = 24
Now we can solve for x:
x = 24 ÷ 0.6
x = 40
So the regular price was $40.
