Kiwis |

$1.50 |
| Total value |
8.4 u |

35% =
35100 =
720Number of guavas = 7 u
Number of kiwis = 20 u - 7 u = 13 u
Price of each guava in percent = 100%
Price of each kiwi in percent = 100% + 25% = 125%
Price of each kiwi
= 1.20 x 125%
= 1.20 x
125100 = $1.50
8.4 u + 19.5 u = 837
27.9 u = 837
1 u = 837 ÷ 27.9 = 30
Cost of the guavas
= 7 u x 1.20
= 7 x 30 x 1.20
= $252
(b)
Number of kiwis ordered
= 13 u
= 13 x 30
= 390
Answer(s): (a) $252; (b) 390
