10 tickets for $1.00 is the better buy because because that would make each ticket 10cents which is cheaper
Answer:
167
Step-by-step explanation:
By BODMAS rule,
13 + 14 x 11
= 13 + ( 14 x 11 )
= 13 + 154
= 167
Note : -
B - Brackets
O - Of
D - Division
M - Multiplication
A - Addition
S - Subtraction
She is incorrect as 10% of the higher marked up price is larger than 10% of the original price.
For example: If you mark up $100 by 10% you get $110.
If you mark down $110 by 10%, you will get $99, as 10% of $110 ($11) is larger than 10% of $100 ($10).
Step 3 is wrong.
It should be 4/7 / 5/8
4/7 x 8/5
32/ 35
The bacteria grow from <span>1,000 bacteria into 12,500 bacteria in 12 hours. The exponent function would be:
an= ao(1+r)^t
12.500= 1,000(1+r)^12
1,000(12.5)= 1,000(1+r)^12
</span>12.5= (1+r)^12
1+r= 1.23427
r= 0.23
Number of bacteria after 20hr would be:
an= ao(1+r)^t
an= 1,000(1+0.23)^20
an= 1,000(62.821 <span>)
an= </span><span>62,821 </span>
