The students of a school numbering 210 raised $175 with which to buy pictures. Seniors gave $ 1.50 each, the rest $ .50 each. Find the number of seniors.

Mr. Mullen has $5.00 in quarters and nickels, having five times as many nickels as quarters. How many coins of each kind does he have ?

@Chelsea98,
1.If the number of seniors is S and there 210 in the school, how many are not seniors?
Then write an equation for the money $175 involving $1.5 times S and $0.5 times (the others). Ignore the dollar signs and solve for S


2.Think about the value of separate piles of 5 nickels +1 quarter,
