The total hire charge in ( £) = number of weeks x 63 + 50 . Susan hires a 3D printer the total hire charge is £743 for how many weeks does Susan hire the 3D printer.
Answer:
Number of weeks = 11
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
