Answer:

The percentage of increase in fuel expenses is 20%

Step-by-step explanation:

Given:

Fuel expense in last year = $800

Fuel expense in this year = $960

To Find:

The percentage of increase

Solution:

Let the percentage increase be X

Then X = $\frac{\text{final value}-\text{starting value}}{\text{starting value}}\times 100$

Now substituting the values we get,

$X =\frac{960-800}{800}\times 100$

$X =\frac{160{800}\times 100$

$X =0.2 \times 100$

X= 20%

The student council at Lincoln Middle School is hosting a school dance. The student council paid $560 for all of the supplies ne

Dovator [93]

Answer:

a) 7t - 560 ≤ 140 is the required inequality to represent the situation.

Step-by-step explanation:

Let t represent the number of tickets sold.

The amount allocated by school council for all supplies = $560

The selling price of each ticket = $7

The aim to earn profit = more than $140

Goal reached if Number of tickets sold = 100

Now, SP of each ticket is $7

⇒Selling price of t tickets = t x ($7) = 7t

PROFIT = TOTAL SELLING Price - TOTAL COST

or, $140 = 7t - $560

According to the question:

7t - 560 ≤ 140

if t = 100, then the profit earned = 7(100) - 560 = 140

Hence, t = 100 is the possible solution of the given expression.
