If a piggybank contains 3.80 in dimes and quarters and there are 20 coins in all what is the formula for how many dimes there are?
let x be number of dimes let y be the number of quarters 10x+25y=380 x+y=20 now we need to manipulate so we can isolate for one variable. y=20-x now we sub into y 10x+25(20-x)=380 expand the expression 10x+500-25x=380 -15x=-120 x=8 therefore there are 8 dimes 8+y=20 y=12 therefore there are 12 quarters
