546 divide by 6 = 91 so 91 times 6 = 546
The expression represents four times the difference of 64 and 18 is
4(64-18)
I hope this correct :)
Commission on the first ten suits: p=5%=0.05
10 * 250 * 0.05 = 2500 * 0.05 = $125
Commission on additional 3 suits:p=5+3=8%=0.08
3 * 250 * 0.08= 750 * 0.08 = $60
In total: 125 + 60 = $185
Answer: His commission was $185.
