What will the sale price be of a t-shirt that has an original price of $24.99 and is on sale for 30% off

Original price $24.99

Now it's on sale with 30% off

So the price now will be 24.99 - 30% of 24.99

Or we can say that it will be 70% of the initial price

So:

24,99 . 70% = 24,99 . 70/100 = 17,493

The price will be $17,493

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

c is the answer
