(1) The admission fee for an exhibition was \$8.50 for each adult and \$3.50 for each pupil. A total of \$5120 was collected. If 160 more pupils than adults visited the exhibition, how many pupils visited the exhibition?

(2) Fiona bought some oranges and 8 mangoes for \$30.80. For every mango she bought, she could buy 4 oranges with the same amount of money. A mango cost \$2.10 more than an orange.
(a) What was the cost of each type of fruit?
(b) Express the number of oranges as a fraction of the total numbers of fruits bought.

Answers (a) - Orange -\$0.70 / Mango-\$2.80

(1) 160 pupils' admission fees = \$160 x 3.5 = \$560
take that from total: \$(5120 - 560) = \$4560
Now, \$(8.5 + 3.5) = \$12
and, \$4560 / \$12 = 380
i.e, 380 adults and (380 + 160) = 540 pupils visited the exhibition.

(2) (a) price of 1 mango (1u) = 4 x price of a mango (4u)
a mango cost \$2.10 more than an orange
that would mean 3u = 2.10
and so, 1u = 0.70
thus, a mango cost \$2.80 and an orange \$0.70

(b) 8 mangoes cost \$2.8 x 8 = \$22.40
thus, \$(30.80 - 22.40) = \$8.20 was the cost of oranges
so that, no. of oranges = \$8.4 / \$0.7 = 12
therefore, fraction of oranges = 12/20 = 3/5
