May I please have help on these problems for my sister?
1 answer:
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.
= ?
? = 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.
