David and his 2 children are going to the zoo. The administration price is
Adult:£60
Children:£67
FAMILY DISCOUND CARD GIVES
1/5 off adults price
60% off child price
Work out the total price David pays after using his discount card.

£92.40

Step-by-step explanation:

Discount price for David =1/5 of 60

= 1/5 × 60/1

= £12 (5 multiplied by 12 is 60)

Price for one child = £67

Price for 2 children= £67 × 2

= 134

Therefore discount price for the children,

134 × 60/100

= 134 × 6/10

= 134 × 3/5

= 26.8 × 3

= 80.4

= £80.40

Therefore total Price David pays,

£80.40 + £12

= £92.40
