| Fruits |
Cost |
| One packet of 2 grapefruits |
$8 |
| One packet of 3 mangoes |
$7.20 |
Number of packets of grapefruits
= 18 ÷ 2
= 9
Cost of the grapefruits
= 9 x 8
= $72
Number of packets of mangoes
= 6 ÷ 3
= 2
Cost of the mangoes
= 2 x 7.20
= $14.40
Total cost for the grapefruits and the mangoes
= 72 + 14.40
= $86.40
Answer(s): $86.40
