Lets be a price of the calculator - $ a
then , after using the coupon, you need to pay $(a-18)
and after using 15% discount , you need to pay (1-0.15)a=0.85a
then, if
(a-18) will be more than 0.85a, you should prefer 0.15 % discount, because it will be cheaper,
a-18> 0.85a
a-0.85a>18
0.15a > 18
a>120, that means that if the price of the calculator more than $120, 15% discount is better,
but if the price of the calculator is less than $120, you should choose $ 18 coupon.
for example, we have the price of the calculator $100
100-18=82,
100*0.85 =85, coupon is better.
If the price of the calculator $200
200-18=182,
200*0.85=170, so 15% discount is better
if price of the calculator is $120,
120-18=102
120*0.85=102,
it will not matter, what you are going to use, because you are going to pay the same amount of money
X= -3x + 2 this is the answer
Answer:
Step-by-step explanation:
The carving was made from a scale model with a scale of 1 inch = 1 foot. This means that one foot on the actual carving is represented by one inch on the model. So the model is smaller than the actual carving.
On the model, Teddy Roosevelt's mustache was 1 foot by 8 inches long.
We would convert the 1 foot on the model to inches because the model is represented in inches
12 inches = 1 foot
This means that on the model, Teddy Roosevelt's mustache was 12 inches by 8 inches long. Therefore,
Teddy Roosevelt's mustache was 12 feets by 8 feets long on the monument or carving
