Answer:
5
Step-by-step explanation:
The exchange rate is 10 CAD = 7 USD
Which means:
10/7 CAD for EACH USD
So, d USD would be:
d * 10/7 = (10d)/7 CAD
This is what she has now, after exchange (in CAD).
She spends 60 and has "d" left, so finding d:
![\frac{10d}{7}-60=d\\\frac{10d-420}{7}=d\\10d-420=7d\\3d=420\\d=\frac{420}{3}\\d=140](https://tex.z-dn.net/?f=%5Cfrac%7B10d%7D%7B7%7D-60%3Dd%5C%5C%5Cfrac%7B10d-420%7D%7B7%7D%3Dd%5C%5C10d-420%3D7d%5C%5C3d%3D420%5C%5Cd%3D%5Cfrac%7B420%7D%7B3%7D%5C%5Cd%3D140)
Hence, d = 140
The digits of d are 1, 4, and 0
The sum is:
1 + 4 + 0 = 5
The sum is 5
You can also approach it this way:
28 flowers times n = 3444
so n = 123
11 x 123 = roses, 17 x 123 = tulips.
Those 2 products should add up to 3444.
