Step-by-step explanation:
PLATO correct
-2=-2y-18
2y=-18+2
2y=-16
Y=-8
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
Answer:
d. 94
Step-by-step explanation:
If business decreases 10%, it is 100% - 10% = 90% of normal.
If business decreases 30%, it is 100% -30% = 70% of normal.
if business is 94% of normal, it is not between these values, so is not a winter business statistic.
