Two friends shop for fresh fruit. elena buys a watermelon for $7.65 and 4 pounds of cherries. taniy buys a pineapple for $2.25 and 3 pounds of cherries. use the variable p to represent the price, in dollars, per pound of cherries.
Answer:Answer: 5.2-p
Step-by-step explanation:
Let p be the price, in dollars, per pound of cherries.
Given : .Jackson buys a watermelon for $7.65 and 5 pounds of cherries.
Cost of 5 pounds of cherries = 5p
Now,
Cost of fruits to Jackson = 7.65+5p (in dollars)
Tim buys a pineapple for $2.45 and 4 pounds of cherries.
Cost of 4 pounds of cherries = 4p
Now,
Cost of fruits to Tim = 2.45+4p (in dollars)
Amount spent by Jackson more than Tim = (Cost of fruits to Jackson)-(Cost of fruits to Tim)
= 7.65+5p -(2.45+4p)
= 7.65+5p -2.45 - 4p
= 5.2-p
Hence , the required expression in terms of p = "5.2-p"

Danny has at least $15 more than his big brother. Danny's brother has 72. How much money does Danny have?
Answer:
d >= $87
Step-by-step explanation:
Since we are not given the exact difference between the amount of money that Danny has in comparison to his brother, then this would ultimately be an inequality question. We are told that Danny has atleast $15 more than his brother, meaning that the minimum that Danny can have is $15 more than his brother. Danny's brother has $72 so we need to add these two values together.
$72 + $15 = $87
Therefore Danny would have a minimum of $87 but at the same time can have more than that. Therefore, we can use the following inequality to represent Danny's money (d)
d >= $87

Mrs. Zahid bought 6 bouquets at $ m each, and 8 packs of chocolates at $ ‘n’ each. She had $(2m + 5n) left. Find the amount of money she had at first.
Answer:
$(8m + 13n)
Step-by-step explanation:
Given that :
Total Cost of 6 bouquet = 6m
Total cost of 8 chocolate = 8n
Total amount spent = $(6m + 8n)
Total amount left = $(2m + 5n)
Hence, amount had at first :
Total amount. Spent + total amount. Left
(6m + 8n) + (2m + 5n)
(6m + 2m + 8n + 5n)
$(8m + 13n)
