Answer:

Number of weeks = 11

Step-by-step explanation:

The total hire charge in £ = number of weeks x 63 + 50.

Her total hire charge = £743

Using the formula

The total hire charge in £ = number of weeks x 63 + 50.

number of weeks = a

743 = a * 63 + 50

743 = 63a + 50

63a = 743 - 50

63a = 693

divide both sides by 63

a = 693/63

a = 11

Number of weeks = 11
