Lisa spent $67 for a skateboard and $25 for a protective helmet.

what percent of the total amount that lisa spent was the price of the skateboard? round to the nearest tenth of a percent, if necessary.

a.
62.7%

b.
72.8%

c.
75%

d.
81.7%

Percent means out of 100 so 
x%=x/100
Lisa spent 67 and 25
what percent was price of skateboard

so percent of total price
total price=skateboard+helmet=67+25=92
total(skateboard and helmet)=92

then percent out of 100
67 out of 92=67/92
one way is to divide fully and get
0.728261/1
make denomentator 100
multiply by 100/100
72.8261/100=72.8261%

the answer is about 72.8%

the answer is B
