Question

Daniela has $35.10 in dimes and quarters. She has 1 more dimes than quarters. How many quarters does she have?

Answer 1

we need to write 2 equations to solve this

Answer 2

let dimes = y
let quarters = x

Answer 3

(.10)y+.25x=35.10 but that doesn't make sense if she has more dimes than quarters

Answer 4

(x+1)10 + (25x) = 3510

Answer 5

O ok.

Answer 6

that would be the first equation right?

Answer 7

Yes that makes sense.

Answer 8

because she has 1 more dime than quarters

Answer 9

(x+1)10 + (25x) = 3510
10x+10 + 25x =3510

35x+10=3510
35x=3500
can you work this out now?
