Question

May I please have help on these problems for my sister?

Answer 1

Answer:

#1: 1) Buying a pack of 3

#2: 2) Jim

#3: 2) 65

#4: 1) $0.04 per fluid ounce

Step-by-step explanation:

#1:

5 shirts for $26.25; divide $26.25 by 5 to get the individual shirt which is $5.25

3 shirts for $14.25; divide $14.25 by 3 to get the individual shirt which is $4.75

10 shirts for $52.25; divide $52.25 by 10 to get the individual shirt which is $5.225 ($5.23).

The cheapest individual shirt is the 3 shirt package.

#2:

Dwight: 3 tickets for $191; divide $191 by 3 to get the individual ticket cost which is $63.67 (Rounded to the nearest hundredth)

Jim: 5 tickets for $309; divide $309 by 5 to get the individual ticket cost which is $61.80

Pam: 7 tickets for $435; divide $435 by 7 to get the individual ticket cost which is $62.14 ( Rounded to the nearest hundredth

Andy: 4 tickets for $256; divide $256 by 4 to get the individual ticket cost which is $64.00

The one who paid the lowest price per ticket is Jim.

#3:

91 portraits in 7 weeks

? portraits in 5 weeks

By cross multiplying, we get 455 portraits in 7weeks*?

To find the unknown, we divide 7 by both sides, leaving the unknown by itself.

$\frac{455}{7}$ = ?

? = 65 portraits

#4:

2-quart bottle for $2.56

1 quart is equal to 32 ounces

Since we know that the bottle cost $2.56, we can divide the cost with the amount of ounces it needs, like the following: $2.56 divided by 64 ounces.

Why 64? The bottle of juice is 2-quarts, so we multiply 32 ounces by 2 to get 64 ounces.

The answer should be $0.04 per fluid ounce.
