Answer:
Step-by-step explanation:
<u>Variable: </u>

<u>Solution:</u>
- 5(3p + 0.97) = 12.89
- 15p + 4.85 = 12.89
- 15p = 12.89 - 4.85
- 15p = 8.04
- p = 8.04 / 15
- p = 0.536
First, you would need to create an equation for this problem. Let x represent the unknown tax.

=

Next, you would cross multiply.
100x = 52.5
Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100.
x = $0.525I hope this helps!
1. The model is <span>14x19x11 centimeters. The ratio is 1 cm : 0.5 m.
14(0.5) = 7
19(0.5) = 9.5
11(0.5) = 5.5
</span>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. <span>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
</span><span>c) 0.63</span>
2.40 / 8 = 0.3
0.3 * 3 = 0.9
Answer: 0.9 is 3/8 of 2.40
