Answer:
18, 21
Step-by-step explanation:
There is a difference of 3 between any two consecutive term ( succeeding - preceding)
Hence 15 + 3 = 18
& 18 + 3 = 21 are the required terms.
If you break it down you will find it
32 blah
16×2 blah
8×2
4×2 the answer is 16
2×2
The total he earns is the sum of two parts. One part is the $200 per car. The other part is the 3% commission.
total earnings = $200 per car + 3% commission on amount of sales
Let's look at the $200 per car first.
He sold 3 cars.
He earns $200 for each car he sells, so just from that he earns
3 * $200 = $600.
Now we look at the 3% commission.
He earns 3% of the total amount of sales.
The total amount of sales for the 3 cars was $32,343.
He earns 3% of that amount, so his 3% commission is
3% of $32,3243 = 3% * $32,343 = 0.03 * $32,343 = $970.29
The total earnings are the sum of the two parts.
$600 + $970.29 = $1570.29
Answer:
The ratio is 4/11
Step-by-step explanation:
Let
x ----> the total number of students in a school
we know that
1) 2/3 of the students study a language.
so
(2/3)x ----> number of students studying a language
and
x-(2/3)x=(1/3)x ---->number of students who do not study a language
2) Of those who study a language 2/5 were studying french
so
(2/3)x(2/5)=(4/15)x ----> number of students studying French
and
(2/3)x(3/5)=(6/15)x ----> number of students studying a language but not studying French
3) we know that
The number of students who do not study French is equal to the number of students who do not study a language plus the number of students who study a language but do not study French.
(1/3)x+(6/15)x=(11/15)x ----> number of students who not study French
(4/15)x ----> number of students who study French
4 ) Find the ratio of students who study french and who do not
(4/15)x/(11/15)x=4/11
