The inverse property of multiplication
Answer:
8c= $225
Step-by-step explanation:
Number of shirts ×cost of each shirt= total cost
Since she bought 8 shirts and the cost of each is c,
8c= $225
To solve for c, divide both sides of the equation by 8:
c= $225 ÷8
c= $28.125
Answer:
The shoes at the other store could be at the most 70.13.
Step-by-step explanation:
In order to find this, we need to set them equal to each other. Start by multiplying the first cost by the amount of the total price you'll be paying.
65.75 * 80%
And the other side would be the amount of the total price being paid times x.
x * 75%
Now set them equal to each other and solve.
65.75 * 80% = x * 75%
52.60 = x * 75%
70.13 = x
X=5/6
(x-1)+x+(x+1)=5/2
x-1+x+x+1=5/2
combine
3x=5/2
divide by 3
x=5/2*1/3
x=5/6
