Nady [450]

Answer:

Total money he had left=629.85

Step-by-step explanation:

We can express Phil's earnings from pizza sales as;

Total earnings from pizza sales=(price per slice×number of pizza slices sold)+(price per whole pizza×number of whole pizzas sold)

where;

Price per slice of pizza=1.75

Number of pizza slices sold=76 slices

Price per whole pizza=9.50 whole pizzas

Number of whole pizzas sold=64

Replacing in the expression above;

Total earnings from pizza sales=(1.75×76)+(9.5×64)=741

Total money he had left=Total earnings from pizza sales-15% of Total earnings

where;

Total earnings from pizzas ales=741

15% of Total earnings=(15/100)×741=111.15

Replacing;

Total money he had left=(741-111.15)=629.85

ivanzaharov [21]

Answer:

2½ h  

Step-by-step explanation:

Assume the graph is like the one below.

The graph shows how Erin's distance varies with time.

To find out how long it takes Erin to cover 25 mi, find 25 mi on the vertical axis.

From there, draw a horizontal line until it hits the graph.

Then drop a vertical line to the horizontal axis.

It hits half-way between 2 and 3.

It takes Erin 2½ h to run 25 mi.

Which box holds more popcorn?
Rashid [163]

Answer:

Amanda's popcorn container holds more popcorn

Step-by-step explanation:

<em><u>First we'll have to find the volume.</u></em>

The Volume helps us determine which is bigger.

<em><u>Step 1</u></em>

We'll find Amanda's popcorn container

10cm*10cm*13.5cm=1350cm

<em><u>Step 2</u></em>

We'll find Mary's popcorn container

8cm*8cm*20cm=320cm

<em><u>Step 3</u></em>

Since Amanda's popcorn container has 1350cm (volume) and Mary's popcorn container has 320cm (volume) we'll have this. 1350cm>320cm. We can determine the Amanda's popcorn container has holds more,

<em><u>Final Answer</u></em>

Amanda's popcorn container holds more popcorn
