1. 86/2=43/new price of one shirt
2. 43-15=28/original price of one shirt
Your answer would be $28.
Answer:
1.4
Step-by-step explanation:
12x+3x=15+6
15x=21
X=21/15
X=7/5 or 1.4
A.) 200+15m=395. This is because the initial price is 200, and after that she will add $15/month. The equation you chose would be exponential, meaning the rate would increase as time passed, which is not the case. Instead, the rate is constant, and the only think that changes is m, the number of months.
b.) I believe it will be easier to answer with ^this equation.
c.) The rate of change would be 15, since the rate is increasing monthly by $15.
d.) Once you solve 209+15m=495, you'll have the answer.
2(c+7)=2c+14
Use distributive property
2*c +2*7
2c+14=2c+14
Hope it helps!
