You buy a shirt for $19.95 and a pair of shorts for $35.95. Shirts are on sale for 25% off and shorts are on sale for 30% off. W

harkovskaia [24]

Discount on shirt, $D_s = 19.95\times 0.25=\$4.9875$ .

So, Price payed for shirt is :

$P=P_s-D_s\\\\P=19.95 - 4.9875\\\\P=\$14.9625$

Discount on shorts, $D_{sh}=35.95\times 0.30=\$10.785$

Discounted price :

$P=P_{sh}-D_{sh}\\\\P=35.95-10.785\\\\P=\$25.165$

Therefore, discounted price of shirt and shorts are $14.9625 and $25.165.

Hence, this is the required solution.
