Answer:
!. Scale factor = 5
2. Scale factor = ![\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D)
Step-by-step explanation:
scale = ![\frac{length in drawing}{actual length}](https://tex.z-dn.net/?f=%5Cfrac%7Blength%20in%20drawing%7D%7Bactual%20length%7D)
1. To increase the numbers, let the scale factor be
= 5. So that;
0.05 x 5 = 0.25
x 5 = 0.5 x 5 = 2.50
7 x 5 = 35.00
13 x 5 = 65.00
25 x 5 = 125.00
102 x 5 = 510.00
2. To decrease the numbers, let the scale factor be
. So that;
0.05 x
= 0.01
x
= 0.5 x
= 0.10
7 x
= 1.40
13 x
= 2.60
25 x
= 5.00
102 x
= 20.40
For this case we have that, the cost of 5 dolls is $130. If we want to know the number of dolls that can be bought with $390 we make a rule of three:
5 dolls -----------> $130
x --------------------> $390
Where the variable "x" represents the number of dolls that can be purchased with $390.
![x = \frac {390 * 5} {130}\\x = 3 * 5\\x = 15](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B390%20%2A%205%7D%20%7B130%7D%5C%5Cx%20%3D%203%20%2A%205%5C%5Cx%20%3D%2015)
Thus, you can buy 15 dolls.
