A table is on sale for $289, which is 32% less than the regular price.
prohojiy [21]

Answer:

R = \$903.125

Step-by-step explanation:

Given

Selling\ Price = \$289

Rate = 32\%

Required

Determine the regular price (R)

From the question, we understand that:

R * 32\% = \$289

So, we have:

R * 0.32 = \$289

R = \frac{\$289}{0.32}

R = \$903.125

<em>Hence, the regular price is $903.125</em>
