The total that Jenny spent is $56.05

<h3></h3><h3>Further explanation</h3>

Jenny buys:

22 pens ⇒ $1.15 each

15 markers ⇒ $2.05 each

Jenny's total spend would be:

= (Pens x price/pen) + (markers x price/marker)

= =\boxed {(22 \times1.15) + (15 \times2.05)\ }\\=\boxed {25.30 + 30.75\ }\\ =\boxed {56.05\ }

Decimal numbers multiplication has the same process as the whole number multiplication, except for the placement of the decimal point in the answer. For example, in multiply 22x1.15 that would be

  1.15     ⇒ 2 decimal place

<u>    22 </u> x <u> </u>⇒ 0 decimal place

 230

<u>230 </u>   +

25.30     ⇒ 2 decimal place

You would do for pens

22 x 1.15 =25.30

And for markets

15 x 2.05 = 30.75

And since you are trying to find how much he spent in all you would add the two sums

25.30 + 30.75 = 56.05

djyliett [7]

Answer:

The probability is 0.0069

Step-by-step explanation:

First thing to do here is to calculate the z-score

Mathematically;

z-score = (x-mean)/SD/√(n)

where x = 9.1 , mean = 8.4 , SD = 1.8 and n = 40

Plugging these values into the z-score equation, we have;

z-score = (9.1-8.4)/1.8/√(40) = 0.7/1.8/6.325 = 0.0615

Now, we check the standard normal table for P(z > 2.46) = 0.0069
