Ric received $3.00 of change. First, you multiply 4 by $1.25 to get $5.00. Then, the pen cost $2.00 because 2 is 2/5 of 5. Next, you add 2 and 5 together to get $7.00. Lastly, you subtract 7 from 10 ($10.00-$7.00) to get your change, $3.00. Hope it helps :)

The probability of having a multiple of 3
Let the event of having a multiple of 3 be represented as: A
So:
So, the probability is:
Where
i.e. the sample size
So:
Sean reads 60 minutes on wednesday
<em><u>Solution:</u></em>
Given that,
Let "x" be the number of minutes read on monday
Let "y" be the number of minutes read on tuesday
Let "z" be the number of minutes read on wednesday
<em><u>He reads 3 times as many minutes on Tuesday as he does on Monday</u></em>
Number of minutes read on tuesday = 3 times the number of minutes read on monday
y = 3x --------- eqn 1
<em><u>He reads 4 times as many minutes on Wednesday as he does on Monday</u></em>
Number of minutes read on wednesday = 4 times the number of minutes read on monday
z = 4x ------- eqn 2
<em><u>Sean reads 45 minutes on Tuesday</u></em>
y = 45
<em><u>Substitute y = 45 in eqn 1</u></em>
45 = 3x
x = 15
<em><u>Substitute x = 15 in eqn 2</u></em>
z = 4(15)
z = 60
Thus he reads 60 minutes on wednesday
X - the first numberx + 13 - the second number
The equation:
x + x + 13 = 152x + 13 = 15 |-132x = 2 |:2x = 1
x + 13 = 1 + 13 = 14
Answer: 1 and 14
