Let's solve it step by step:
(we start with the innermost bracket: (25/5). This is equal to 5. :
25+{2[3+8-7(25/5)+11]} =
25+{2[3+8-7(5)+11]} =
now, we can multiply 7 and 5, which is 35
25+{2[3+8-35+11]} =
Now we can add all the numbers in the square bracket, 3,8 (that's 11), then -35 (which is -24) then 11 - all together it's -13
3+8-35+11=22-35=-13
25+{2[-13]} =
Multiplying 2 and -13
25+{-26} =25-26, which is -1
the final answer is -1
Answer: 4/6+4/6 is 8/12 and bigger than 3/5
Step-by-step explanation:
Answer:
she is wrong, offer 2 results in lower interests
Step-by-step explanation:
total amount paid if offer 1 is accepted:
$6,000 x (1 + 3%)² = $6,000 x 1.0609 = $6,365.40
she will pay $365.40 in interests
total amount paid if offer 2 is accepted:
($6,000 x 1.01) x 1.05 = $6,060 x 1.05 = $6,363
she will pay $363 in interests
Compounding interest refers to interest that earns more interest itself, e.g. in the first offer, the $180 of interests charged for the first year will earn $5.40 in extra interests. While offer 2 only charges $60 in interests during the first year which will in turn earn $3 of interests. The difference between both offers is that interest charges in offer 1 earn more interests than the interest in offer 2 = $5.40 - $3 = $2.40
