Answer:
The total price of pounds of apples is <u>$6.48</u>.
Step-by-step explanation:
Given:
Last week,the price of apples at a grocery store was 1.60 per pound.This week,apples at the same grocery store are on sale for a 10% discount.
Now, to find the total price of 4 1/2 pounds of apples this week at the grocery store.
The price of apples at a grocery store last week was = $1.60 per pound.
This week apples at the same grocery store is on sale of 10% discount.
Thus, the price of apples at a grocery store this week is:
So, the price of apples per pound this week is $1.44.
Now, to get the total price of pounds of apples by using unitary method:
If 1 pound of apples cost =
Then, pound of apples cost =
Therefore, the total price of pounds of apples is $6.48.
Probability is defined as the <u>likelihood or the certainty</u> that an event is going to<u> occur or happen.</u>
The probability of randomly choosing a red and then a green marble is .
The total number of marbles = 20
The number of green marbles= 3
The number of blue marbles = 12
The number of red marbles = 5
<u>The probability of choosing a red marble</u> = Number of red marbles / Total number of marbles
= 5/20
<u>In simplest fraction form</u> =
We are told in the question that you keep the red marble you choose, So this means the <u>total number of marbles</u> left reduces to 19
<u>The probability of choosing a green marble is</u> = Number of green marbles / New total number of marbles
= 3/19
Therefore, <u><em>the probability of randomly choosing a red and then a green marble is </em></u>
P (Red) x P(Green)
= 1/4 x 3/19
=
