Sarah bought 3 first class tickets and 7 coach tickets.

Step-by-step explanation:

Given,

Number of people = 10

Total amount spent on tickets = $4830

Cost of each coach ticket = $270

Cost of each first class ticket = $980

Let,

x be the number of coach tickets

y be the number of first class tickets

According to given statement;

x+y=10      Eqn 1

270x+980y=4830   Eqn 2

Multiplying Eqn 1 by 270

270(x+y=10)\\270x+270y=2700\ \ \ Eqn\ 3\\

Subtracting Eqn 3 from Eqn 2

(270x+980y)-(270x+270y)=4830-2700\\270x+980y-270x-270y=2130\\710y=2130

Dividing both sides by 710

\frac{710y}{710}=\frac{2130}{710}\\y=3

Putting y=3 in Eqn 1

x+3=10\\x=10-3\\x=7

Sarah bought 3 first class tickets and 7 coach tickets.

The table below shows the number of skateboards sold at a skate shop each week for five weeks.
hammer [34]

Answer:

s = 22w

Step-by-step explanation:

We need to try this equation for all of the numbers in the table.

s = 22w

22 = 22 * 1

s = 22w

44 = 22 * 2

s = 22w

66 = 22 * 3

s = 22w

88 = 22 * 4

s = 22w

110 = 22 * 5
