9514 1404 393

Answer:

Step-by-step explanation:

Let d represent the number of donuts. The cost is proportional to the number, so we have ...

d/33.00 = 9/5.50

d = 33.00(9/5.5) = 9·6 = 54

You can buy 54 donuts for $33.00.

Answer:

${7a^{5}b^{5} c\\$

Step-by-step explanation:

$\frac{28a^{8}b^{6} c^{3} }{4a^{3}bc^{2} }$

→ First look at the first term of each expression and see if they can be simplified, and they can

$\frac{7a^{8}b^{6} c^{3} }{a^{3}bc^{2} }$

→ Now look at the a terms, since a larger one is at the top, you subtract

$\frac{7a^{5}b^{6} c^{3} }{bc^{2} }$

→ Now simplify the b and c terms

${7a^{5}b^{5} c$
