Artemon [7]3 years ago

Original ratio: 3 + 8 = 11

240/11 = 21.818

3 x 21.818 = 65.5

11 x 21.818 = 174.5

New ratio: 3 + 2 = 5

240/5 = 48

3 x 48 = 144

2 x 48 = 96

Number of stamps bought = new amount - original amount:

144-65.5 = 78.5

Round to nearest whole number = 79 stamps bought

Assume the normal quantity of cookies is x.

The demanded quantity by the stores now:
0.5x
The previous cost is: $4 * 0.5x = $2x

The cost of demanded quantity by the stores now: $5 * 0.5x = $2.5x

The price elasticity of demand: $2.5x - $2x = $0.5x

a taxi service charges an initial fee of $5 plus $1.80 per mile. How many miles can you travel for $12
user100 [1]
First you need to write an equation or an inequality.

5+1.80x<=12 
the x here is how many miles you are paying for, now you just solve for x. 

5+1.80x<=12
-5                 -5

1.80x<=7
/1.80         /1.80
x<=3.8

you can travel only three whole miles, you do not have enough money to go four full miles.
