Answer 2

Step-by-step explanation:

Step-by-step explanation:

First you need to find what

40

%

of

180

is.

To find

10

%

of a number you have to move the decimal place back by one.

For example,

10

%

of

120.0

would be

12.00

(

12

)

.

Using this technique we find that

10

%

of

180

is

18

.

now we times

18

by

4

to create 40% of the cost.

18

×

4

=

72

Now minus 72 from 180 (the total cost of the bike).

180

−

72

=

$

108

So , this means Jenny paid $108 for her bike.
