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%

So,

The skateboard cost $67.
The protective helmet cost $25.

To find the percent that the price of the skateboard was out of the total amount, add 67 and 25 and divide 67 by the result.

Step 1:
67 + 25 = 92

Step 2:
67/92 = 0.728 or 72.8%.

The correct option is B.

So percent means parts 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
so total=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 aprox 72.8%

the answer is B

Yes, it is a variable quantity because the number of rides he goes on depends on the length of the lines which are unpredictable.
