Answer:
45 members are in the choir.
Step-by-step explanation:
Set up an equation:
Variable x = boys
3/6 = x/30
Cross multiply:
3 × 30 = 6 × x
90 = 6x
Divide both sides by 6:
15 = x
There are 15 boys.
To find the number of members in the choir, add the number of boys and girls:
30 + 15 = 45
The answer would be $10.31 us dollars
0.44 / (0.06 + 0.09) = 0.44 / 0.15 = 2.93....about 3 hrs
Multiply the cost by 1 + markup :
180 x 1 +0.55 =
180 x 1.55 =279
The answer is D. $279
