Maths for Business TMA Week 1
Question 1
A magazine pays different rates for Star Letters and Readers' Letters.
In June the magazine editor paid out £1090 for 3 Star Letters and 8 Readers'
Letters.
In July £1180 was paid out for 2 Star Letters and 11 Readers' Letters.
How much does the magazine pay for each type of letter?

Star Letter Costs: £150

Reader Letter Costs: £80

Explanation:

Represent Star Letters with S and Reader's Letters with R

Given

Required

Determine the value of R and S

Multiply the first equation by 2 and the second equation by 3; to eliminate S

Subtract the resulting equations

Divide both sides by -17

Substitute 80 for R in the first equation

Subtract 640 from both sides

Divide both sides by 3

Hence:

Star Letter Costs: £150

Reader Letter Costs: £80

if you use only 25 for your entertainment and only 200 for the groceries that you really need and take out the 50 per month for the computer then that should be enough

the answer is     d. in our global economy, most job growth will be in services, but manufacturing jobs will exist, too.
