Answer: 2 enlargments
Step-by-step explanation:
Use proportion for each enlargment you do
Side a=6cm Side b=4cm
6:4=x:7 4:4=b1:7
7*6=4a1 b1=28/4
a1=42/4 b1=7 after first enlrge
a1=10.5 after first enlarge 7:4=b2:7
10.5:4=a2:7 b2=49/4
a2=73.5/4 xb2=12.5 after 2nd enlarge
a2=18.375 after 2nd enlarge
12.5:4=b3:7
18,375:4=a3:7 b3=21.875 cm after 3rd enlargement
a3=32.15after 3rd enlargement
Values after 3rd enlargement are higher than dimension given for picture wall
30 cm by 20 cm
I believe the answer is B but i could be wrong, sorry.
48.99 x 6.25 = 306.1875
Sales tax = $3.06
$48.99+3.06 = $52.05
If it depreciates 48%, then its value is (100% - 48%) = 52%
52% of 43,900....
0.52(43900) = 22,828 <==
