nadezda [96]

Answer:

Discount percentage = 10.5% (Approx)

Therefore the discount is seller offering you is 10.5 % .

Step-by-step explanation:

Discount = Marked price - Selling price

As given

\frac{2.1 x 100}{19.95}

\frac{210}{19.95}

Discount percentage = 10.5% (Approx)

Therefore the discount is seller offering you is 10.5 % .

DedPeter [7]
So

x=hours
y=pay

use a piecewise function maybe

for x≤40, use y=21x


for x>40, use 840+1.5(21(x-40))


k, sso 46>40 so

840+1.5(21(46-40))
840+1.5(21(6))
840+1.5(126)
840+189
1029



A. 840+1.5(21(x-40))

zysi [14]
