Question

Jenny buys 22 pens that cost $1.15 each and 15 markers that cost $2.05 each. How much did Jenny spend?​

Answer 1

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

Answer 2

The total that Jenny spent is $56.05

Further explanation

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

   22 x ⇒ 0 decimal place

 230

230   +

25.30     ⇒ 2 decimal place
