4. Dan and Laura had to pay to sign up for swim lessons, and then they paid a certain amount per lesson. Dan

natali 33 [55]

Answer:

Mitch has taken 17 complete lesson and 60% of one last lesson.

Solution:

Dan and Laura needs to pay certain amount for swimming lessons.

Dan took four lessons and paid $ 100

Laura took 8 lessons and paid $ 200.

Need to calculate number of lessons taken by Mitch when amount paid by Mitch = $440.

Let’s first calculate price of one lesson.

For 4 lessons of Dan, payment = $100

So for 1 lesson of Dan, payment $\frac{100}{4} = 25$

For 8 lessons of Laura, payment made = $200

So for 1 lesson of laura, payment made = $\frac{200}{8} = 25$

So clearly cost of 1 lesson = $ 25.

So number of lessons taken by Mitch = Amount spent / cost of 1 lesson

$= \frac{440}{25} = 17.6$

So Mitch has taken 17 complete lesson and 60% of one last lesson.

What is unit price ? Use in your own words .

dezoksy [38]

Unit price means the cost per unit.

I'll provide an example.

If 4 bars of soap cost $2.35, find the unit price. Round to the nearest cent if necessary.

Remember that the unit price is the cost per unit which in this case is the cost per bar of soap. Since $2.35 is the cost for 4 bars of soap, to find the cost per bar of soap, we divide 4 into $2.35.

When we do this, we get an answer of 0.587 which rounds up to 59 cents.

Therefore, the unit price for soap is 59 cents.

Hannah finds purple, blue, and silver space rocks while exploring.

Maru [420]

To answer this, you will determine what fraction of the original rocks are silver by using the information about the other two colors.

If 2/3 of them area purple, than 1/3 are not.

If 3/4 of the remaining 1/3 is blue, than 3/4 x 1/3 = 3/12 of then are blue.

2/3 are purple, 3/12 of them are blue, the remaining is silver,

1 - 2/3 - 3/12
1 - 8/12 - 3/12 = 1/12

1/12 of the rocks are silver. If 3 are silver, write an equation that needs solved.

1/12r = 3
r = 36 rocks

There were 36 space rocks in total.
