If Two Cans Of Paint Can Cover 750 Square Feet How Much Money Would It Cost To Paint 15000 Square Feet At 25 Per Can And A Sales Tax Rate Of 7 class=

Sagot :

Given

2 cans cover 750 square feet

x cans cover 15000 square feet

Then, find x:

[tex]\begin{gathered} 750\times x=15000\times2 \\ 750x=30000 \\ \frac{750x}{750}=\frac{30000}{750} \\ x=40 \end{gathered}[/tex]

This is, 40 cans of paint can cover 15000 square feet.

On the other hand, we have:

1 can has a price of $25, so

[tex]40\times25=1000[/tex]

Therefore, 40 cans have a price of $1000

And finally, the sales tax rate is 7%, this is:

[tex]1000\times\frac{7}{100}=1000\times0.07=70[/tex]

Hence, the total cost is

[tex]1000+70=1070[/tex]

Answer: E. $1070
