If I can speak 150 words in one minute, how many words can I speak in 23 minutes?
150/1 = x/23
1x = (150)23
x = 3,450 words

What is the percent of change?
Gas cost $1.99/gal. in 2016 and in 2026 costs $4.55/gal. classify as a percent increase or decrease.
1.99 - 4.55/1.99 = 2.56/1.99 = 1.2864
= 128.6% increase

How do I solve for x to find the degree measure of an UNKNOWN angle in a triangle?
Find the SUM of all the angles = to 1800
8x - 1 + 3x + 4 + 3x + 9 = 180
=14x +12 = 180
-12 -12
14x = 168
⌹ 14 ⌹ 14
x = 12

What is the interest earned formula?
Solve: 8% interest on a $12,500 loan for 5 years
I=prt
Interest = principal(rate)(time)
I = 12,500(.08)(5)
I = $5,000

How do I solve for x with vertical angles? (3x +6)0 and (13x - 14)0
Set the two angles opposite each other = to each other
(3x + 6) = (13x - 14)
-13x - 6 -13x - 6
-10x = -20
x = 2

Find the total paid back after 5 years:
Solve: 8% interest on a $12,500 loan for 5 years
I = 12,500(.08)(5)
I = $5,000
12,500 + 5,000 = $17,500

A $29.95 item is on a 20% discount. Find the total amount after paying 8% sales tax
29.95(.20) = $5.99 discount amount
29.95 - 5.99 = $23.96
23.96(1.08) = $25.88
