Which expression is equivalent to 100

a coach bought three soccer balls on sale. they normally sell for $26 each. they were on sale for $7 off the original price. the

Rom4ik [11]

Answer:

The coach paid $69 on the three soccer balls

Step-by-step explanation:

If the coach bought 3 soccer balls for 26$, minus the $7 on each, plus the $4 tax on each, the expression would be:

3 × (26 - 7 + 4)

We put the addition and subtraction in parentheses because of PEMDAS. PEMDAS say we must solve for whatever is in the parentheses first, then exponents (there are none in the expression), ans then multiplication. If those numbers were not in parentheses, the answer would look completely different as we would multiply before subtracting and adding. We must find the total amount each ball cost first:

26 - 7 + 4 = 23

Each ball cost $23

If the coach bought 3 balls for $23 each, we have to multiply the two numbers:

3 × $23

$69

Answer:

a) 62%

b) 44%

Step-by-step explanation:

Beforehand we have the information that the amount of shoppers, let`s call it n= 150.

To answer the first question, we need to know the amount of shoppers that do not possess an email account: this is the sum= 18`+75 (both the shoppers without and with access to a computer at home buth without an email). Lets call it a.

The percentage is defined by:

%of shoppers that dont have and email account= a/n*100= (18+75)*100/150= 62%

The next question is the percentage of shoppers with computer access at home, thus the sum of 48+18, both who have and dont have an email account but the have computer access at home. Lets call it b.

So

%of shoppers that have computer access at home = b/n*100= (48+18)*100/150= 44%

What is the net change in how many bags are on the shelf from

Temka [501]

Answer:

-2

Step-by-step explanation:

The computation of net change from the beginning of Tuesday to the end of Monday is shown below:-

The change at the last of Tuesday

Change = Restock - Sales

= 6 - 5

= 1

Here it indicates that the number of bags is rise by 1

The change at the last of Wednesday

Change = Restock - Sales

= 12 - 8

= 4

Here it indicates that the number of bags is rise by 4

The change at the last of Thursday

Change = Restock - Sales

= 12 - 2

= 10

Here it indicates that the number of bags is rise by 10

The change at the last of Friday

Change = Restock - Sales

= 18 - 19

= -1

Here it indicates that the number of bags is fall by -1

The change at the last of Saturday

Change = Restock - Sales

= 24 - 22

= 2

Here it indicates that the number of bags is rise by 2

The change at the last of Sunday

Change = Restock - Sales

= 0 - 15

= -15

Here it indicates that the number of bags is fall by -15

The change at the last of Monday

Change = Restock - Sales

= 0 - 3

= -3

Here it indicates that the number of bags is fall by -3

According to the given situation, it is equivalent the algebraic sum of every change

So,

Net change = 1 + 4 + 10 + (-1) + 2 + (-15) + (-3)

Using associative property: (1 + 4 + 10 + 2) - (1 + 15 +3)

Simplifying: 17 - 19 = -2
