btw to multipy percent w a whole number you have to make the percent into a decimal. and move the decimal point 2 times to the left
ex, 15% converted into a decimal 0.15
and then u multiply with the whole number, 1500 times 0.15
which equals 225, and lastly u subtract 225 from 1500 (1500-225)
& u get $1275
B is the correct answer distributive property
