Answer:
Mom: $30
Charlie: $10
Step-by-step explanation:
You have to find how much percent of 40 for the price that they each pay.
His mom pays 75%, so that is $30.
And Charlie has to pay $10 because that is how much is left.
Answer:
He bought 1 small bag and 6 large bags.
Step-by-step explanation:
We can set up 2 equations with the given information.
5x+8y=45
x+y=6
We can rearrange the second equation to solve for x.
x=6-y
Now we substitute x for 6-y in the first equation
5(6-y)+8y=45
30-5y+8y=45
30+3y=45
y+10=15
y=5
x=1
He bought 1 small bag and 6 large bags.
Hello!
The chance of getting a football card is 7 / 10
The chance of then getting a basketball card is 3 / 10
Multiply these two numbers
7/10 * 3 / 10 = 21/100
21/100 = 0.21
The answer is 0.21 or 21%
Hope this helps!
