yes sure, i learned this before so
1. a. make a proportion here, of percentage.
if you cross multiply and divide you get 90%.
1. b. obviously the empty seats would be 10%.
2. a. proportion again,
cross multiply then divide you ge 15%
3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5
Answer:
1%
Step-by-step explanation:
S.P of each radio=$ 2288
Total S.P=
$4576
Gain=10%
Lose=10%
C.P=
C.P=
By using the formula
C.P of one radio=
$2080
C.P of another radio=
=$2542.2
Total C.P of two radios=2080+2542.2=$4622.2
Total C.P >Total S.P
Loss=S.P-C.P
Loss=4622.2-4576=$46.2
Loss%=
Loss %=
1%
Hence, his loss 1%
Let
b---------> <span>the cost of one flower bouquet
</span>v--------> <span>the cost of one vase.
we know that
2b+2v=12.50-----> </span>Multiplied by -1------------->-2b-2v=-12.50
8b+2v=29---------------------------------------------> 8b+2v=29
I add the two equations ------------------------
6b=16.50
b=2.75
2*2.75+2*v=12.50---------------> v=(12.50-5.5)/2---------> v=3.5
the answer is
the cost of one flower bouquet is $2.75
the cost of one vase is $3.5
x+5= 10
move +5 to the other side
sign changes from +5 to -5
x+5-5= 10-5
x= 10-5
x= 5
Answer:
x= 5
