Mathematics

gladu [14]3 years ago
5 0

Let Morgan = X

Then Mary = 5X ( 5 times as old).


The sum is 72, so 5x +x = 72

5x +x = 6x:

6x = 72

Divide both sides by 6:

x = 72 / 6

x = 12

Morgan is 12 years old.

Mary is 5(12) = 60 years old.

A baker purchases flour each week from a wholesale warehouse. The chart shows the quantities and prices available this week. If
scZoUnD [109]

The chart showing the quantities and prices is;

Best Deal 1

Quantity of Flour Price

3 pounds $5.25

5 pounds $9.75

7 pounds $12.60

10 pounds $14.20

12 pounds $18.24

Answer:

difference between last weeks best deal = $0.3

Step-by-step explanation:

Let's calculate the unit price for each of the quantities in the chart.

For quantity of 3 pounds;

We have; unit price = 5.25/3 = $1.75

For 5 pounds;. Unit price = 9.75/5 = $1.95

For 7 pounds; unit price = 12.6/7 = $1.8

For 10 pounds; unit price = 14.2/10 = $1.42

For 12 pounds; unit price = 18.24/14 = $1.3

Thus, last weeks best deal is the lowest = $1.3

Thus; difference between last weeks best deal is given as;

= this weeks best deal - last weeks best deal

This gives;

$1.6 - $1.3 = $0.3
