A plant nursery is having a sale. Potted begonias are marked down 27%, and tomato seedlings are marked down 35%. If you pay $6.
olchik [2.2K]

Based on the markdowns and the number of each of the plants purchased, the amount saved is <u>$9.06</u>

Potted Begonias cost $6.57 when discounted by 27%. Their cost must be:

<em>Discounted cost = Original cost x (1 - Discount)</em>

6.57 = Original x (1 - 27%)

Original = 6.57 / 0.73

Original = $9.00

The savings here are therefore:

= 2 x (9 - 6.57)

= $4.86

The original cost of the Tomato seedlings is:

= 2.60 / ( 1 - 35%)

= $4.00

Savings would be:

= 3 x (4 - 2.60)

= $4.20

Total savings are therefore:

= 4.86 + 4.20

= $9.06

In conclusion, $9.06 was saved.
