5 t-shirts and a hat costs £62.00 2 t-shirts and a hat costs £29.00.
How much does a t-shirt cost?
How much does a hat cost?

T-shirt : £11

Hat : £7

Step-by-step explanation:

Think of T-shirts as T

and Hats as H

5t + h = 62

2t + h = 29  

we then subtract them both to cancel out h

3t = (62-29) = 33

now we divide 33 by 3  to find one t

33/3 = 11

so one t shirt is £11.00

now we substitute it back into the equation

2t ( 2x11 ) = 22

22 +h = 29

29 - 22 = 7

so then what are you asking?

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
