Application word problems

Postby Jennynguyen_22 on Fri Feb 07, 2014 11:58 pm

I've always had problems with word problems. Please help...

1) The tickets for a local production cost $6.00 for adults and $3.00 for children and seniors. The total receipts for 505 tickets were $1977. Find the number of adult tickets sold.


2) A silversmith combined pure silver that costs $5.20 an ounce with 50 oz of a silver alloy that costs $2.80 an ounce. How many ounces of the pure silver were used to make an alloy of silver that costs $4.40 an ounce?
