Answer:
The first one $1.42
Step-by-step explanation:
1.42x5=7.1 (cost of all envelopes)
12-7.1=4.9
4.9/14=0.35 (one postcard)
10 postcards= 3.5
1.42x15=21.3 (cost of all envelopes)
3.5+21.3=$24.80
If im not wrong since the scale factor from A to B is 1:4, that means if you multiply 8 x 4
You will get 32, which is the size of B. Hope this helps!
