Answer 1

(7)

One mug holds 450 mL of tea

Another mug holds 0.65 L of tea

1 L = 1000 mL

0.65 L = 0.65*1000

= 650 mL

Another mug holds more tea.

Ms. Ru should buy another mug which can holds 650 mL of tea because she loves tea and she wants the biggest mug possible.

(8)

Vendor sells beans for $3 per cup

Or $5 per quart

1 quart = 4 cups

That means price of beans per cup = 5/4

= $1.25

In second option vendor sells beans for $1.25 per cup

Second option is cheaper hence second option is better

$5 per quart is better to buy

(9)

A Vendor sells soups for $1.25 per cup

Or $3.75 per quart

1 quart = 4 cups

That means price of soups per cup = 3.75/4

= $0.9375 per cup

In second option vendor sells soups for $0.9375 per cup.

Second option is cheaper hence second option is better

$3.75 per quart is better to buy.

Thank you :)
