the initial price of a home entertainment system is $34,000. It is discounted by 10% and then by a further 26%. Find the price o
maria [59]
The final price of the item is $22,644

The initial discount of 10% leaves the price at 90% of the retail value:
\frac{x}{34000}  =  \frac{90}{100}
cross multiply to solve for x:
100x = 3,060,000
x = 30,600
This new price is then discounted 26%, which means the final price is 74% of $30,600:
\frac{x}{30600}  =  \frac{74}{100}
cross multiply to solve for x:
100x = 2,264,400
x = 22,644
The final price of the home entertainment system is $22,644

1 pizza costs £3.20 more than a bottle of coke. The total cost of the items is £19.40 for 3 pizzas and 1 bottle of coke
Korolek [52]

1 pizza should cost $5.65

Pizza is $5.65 then bottle of coke is $2.45

3 pizzas and coke: ($5.65*3) + $2.45 = $19.4

I solved this by setting up and solving a system of linear equations:

Variables: p = pizza, c = coke

p = c+3.2

3p+c = 19.4

Solve by substitution

3(c+3.2) + c = 19.4

4c+9.6 = 19.4

c = 2.45

Re-plug in:

p = 2.45+3.2

p = 5.65
