Starfruits |
Pears |
| Numbers |
7 u |
13 u |
| Price |
$2.50 |
$3.50 |
| Total value |
17.5 u |
45.5 u |
35% =
35100 =
720Number of starfruits = 7 u
Number of pears = 20 u - 7 u = 13 u
Price of each starfruit in percent = 100%
Price of each pear in percent = 100% + 40% = 140%
Price of each pear
= 2.50 x 140%
= 2.50 x
140100 = $3.50
17.5 u + 45.5 u = 1323
63 u = 1323
1 u = 1323 ÷ 63 = 21
Cost of the starfruits
= 7 u x 2.50
= 7 x 21 x 2.50
= $367.5
(b)
Number of pears ordered
= 13 u
= 13 x 21
= 273
Answer(s): (a) $367.5; (b) 273
