Answer:
Kayla = $20.14
Michael = $19.08
The Difference = 1.06
Step-by-step explanation:
<em><u>How to solve.</u></em>
First, you need to add up how much Kayla is paying for the video game, plus the 6% tax.
19.00 + 6% = 20.14
Then, you need to do the same with Michael's.
18.00 + 6% = 19.00
To find the difference between how much Kayla and Michael paid for their items, you need to subtract their total.
20.14 - 19.00 = 1.06
and the nearest cent would be 1.10.

ANSWER
250g of Roquefort cheese will cost
£2.8
EXPLANATION
If 150g of roquefort cheese cost £1.68, we can write the ratio,

Let 250g of Roquefort cheese cost £x.
Then we can again write the ratio,

We can equate the two ratios and solve for x.

We rewrite the ratios as fractions to obtain,

We cross multiply to get,

This implies that,

Divide both sides by 150 to get,


Therefore 250g of Roquefort cheese will cost
£2.8
The radius is 5 so you can add 5 to the y value of the center to get (3,8)
