Answer:

\frac{9}{10}x  = 18

\frac{2}{3}y  = 18

we can make these two equations.

solve for x and y:

\frac{9}{10} x \div \frac{9}{10} = 18 \div  \frac{9}{10}

x = 20

\frac{2}{3} y + \div  \frac{2}{3}  = 18 \div 2 \frac{2}{3}

y = 27

The total number can be calculated by:

x + y = 20 + 27 = 47

Your answer:

47

which is D.
