Tanya has bills worth $40 in her wallet. If she has one more $5 bill than $10 bills and two more $1 bills than $5 bills, how many of each does she have?

Answer 1

Yes 1x + 5 y + 10 w = 49

other equations are

y = w + 1 and x = y + 2

solve both for y, then substitute into original equation

1(y + 2) + 5 y + 10(y - 1) = 40

solve for y the find other answers by substitution

x = 5. y = 3. w = 2

Answer 2

x = number of $1 bills

y = number of $5 bills

z = number of $10 bills

1(x) + 5(y) + 10(z) = 40

1(5) + 5(3) + 10(2) = 5 + 15 + 20 = 40

Tanya has 5 $1 bills, 3 $5 bills, and 2 $10 bills.
