The scott family is trying to save as much money as possible. one way to cut back on the money they spend is by finding deals while grocery shopping; however, the scott family needs determining which stores have the better deals.

1. at grocery mart, strawberries cost $2.99 for 2 lb., and at baldwin hills market strawberries are $3.99 for 3 lb.
a. what is the unit price of strawberries at each grocery store? if necessary, round to the nearest penny.
b. if the scott family wanted to save money, where should they go to buy strawberries? why?

2. potatoes are on sale at both grocery mart and baldwin hills market. at grocery mart, a 5 lb. bag of potatoes cost $2.85, and at baldwin hills market a 7 lb. bag of potatoes costs $4.20. which store offers the best deal on potatoes? how do you know? how much better is the deal?

Step-by-step explanation :

1.a. The price of 2 pound strawberries at Grocery Mart = $2.99

The price of strawberries per pound at Grocery Mart =

                                                                                 = $1.495 ≈ $1.50/lb

ant the price of 3 pound strawberries at Baldwin Hills = $3.99

The price of strawberries per pound at Baldwin Hills =

                                                                                       = $1.33/ lb

The unit price of strawberries at Grocery Mart is $1.50 and at Baldwin Hills is $1.33.

b. If the Scott family wanted to save money, they should go to Baldwin Hills because at Baldwin Hills the price of one pound strawberries is less than Grocery Mart.

2. The price of 5 pound bag of potatoes at Grocery Mart = $2.85

The price of 1 pound potatoes at Grocery Mart =

                                                                           = $0.57/lb

The price of 7 pound bag of potatoes at Baldwin Hills = $4.20

The price of 1 pound of potatoes at Baldwin Hills =

                                                                           = $0.60/lb

At grocery mart the unit price of potatoes is $0.57 and at Baldwin Hills unit price of potatoes is $0.60.

Therefore, at Grocery Mart is the better deal.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
