Answer:

1016.50

Step-by-step explanation:

$21.40 per hour at her job for the first 40

21.40 * 40 =856

She has 5 hours over 40  (45-40 =4)

That means 5 hours at 32.10

5 * $32.10 =160.5

Add the two amounts together

856+160.5

1016.50

2/3 cup of oatmeal is needed to make 10 granola bars. how many such granola bars can be made with 20 cups of oatmeal? Kindly ple

2/3 cup of oatmeal - 10 granola bars

When the number of cups of oatmeal increases, the number of granola bars also increases.
If you use for example twice as many cups of oatmeal, you'll make twice as many granola bars.
Therefore, the first step is to calculate how many times 20 cups of oatmeal is more than 2/3 cup of oatmeal. To do it, divide 20 by 2/3.

20 \div \frac{2}{3} = 20 \times \frac{3}{2}=\frac{60}{2}=30

You have 30 times as many cups of oatmeal, so you'll make 30 times as many granola bars.

10 \times 30= 300

300 granola bars can be made with 20 cups of oatmeal.

Jo's mother, Anne, is four times as old as Jo. In four years time, Anne will be three times as old as Jo. How old is Jo? (this i
pentagon [3]

Answer:

Jo's age = x = 8 years

Step-by-step explanation:

Let

Jo's age = x

Jo's mother, Anne's age = 4x

In four years time, Anne will be three times as old as Jo.

Jo's age =3( x + 4)

Jo's mother, Anne's age = 4x + 4

How old is Jo?

Equate Jo's age and his mother's age

3(x + 4) = 4x + 4

3x + 12 = 4x + 4

3x - 4x = 4 - 12

-x = - 8

Divide both sides by -1

x = 8

Therefore,

Jo's age = x = 8 years
