Answer:
£162.35.
Step-by-step explanation:
Total of letters + packages = 300.
Number of packages = 300 * 16 / ( 16+59)
= 300 * 16/75
= 64
So number of letters = 300 - 64 = 236.
No. of first class letters = 236 * 1/4 = 59.
No. of 2nd class letters = 236 - 59 = 177.
Total cost
= 64*1.2 + 0.52*59 + 0.31*177
= 162.35.
Answer:
one of the quantities is a constant multiple of the other, or equivalently if they have a constant ratio
Step-by-step explanation:
Simpe interest rate = PRT/100
— ( principal x rate x time ) / 100
$3,000 is the principal
3 years is the time
2% is the rate
so, PRT/100
(3,000 x 3 x 2) / 100
= $180
Answer : $180
<span>Megan
went to beach 34 times last summer.
June = x
July = 6 * june
August = 2 * june
Thus Let’s find the value of june, which is the value of x as a variable:
Equation:
x + 6x + 2x = 34
Solution:
=> x + 6x + 2x = 34
=> 9x = 34
=> 9x / 9 = 34 / 9
=> x = 3.7778, since this is a decimal, let’s round this off to 3.78
Let’s check our answer
=> 4 + 6(4) + 2(4)
=> 4 + 24 + 8
=> 36 approximately.</span>
