1. The model is 14x19x11 centimeters. The ratio is 1 cm : 0.5 m.
14(0.5) = 7
19(0.5) = 9.5
11(0.5) = 5.5
7x9.5x5.5 meters
b) 365.75 m^3

2. To find the money spent on food, all you do is find the percent of food of the total income. food = 35%, income = $2000
35% of 2000
0.35(2000)
a) $700

3. 4.8x-1.3=1.7
First add 1.3 to both sides to cancel it out.
4.8x = 3
Divide both sides by 4.8.
x = 0.625
c) 0.63
