Georgia lifts free weights. the bar weighs 25 pounds. she puts two 25-pound weights and two 10-pound weights on the bar. how much do the bar and the weights weigh together?

First you will add 25+25=50-pounds 
Second you will add 10+10=20-pounds
Third you will add 50+20=70-pounds for all the weights
Fourth you will add the total pounds of all the weights and the weight of the bar 70+25=95
So, the answer would be 95-pounds.
Hope this helps! Have a good day!
