A store is selling ribbon by the yard. Mike bought 8 yards of red ribbon. Each yard cost $3.50. Complete and solve the working equation that represents the amount, a , Mike paid for buying 8 yards of ribbon.
a/8=
a= $
a/8 = 3.50
To solve for a, we multiply both sides of the equation by 8:
8 * a/8 = 8 * 3.50
This simplifies to:
a = 28
Therefore, Mike paid $28 for buying 8 yards of ribbon.
A store is having its year-end sale. A shirt now costs $7.98, which is half of its original price. Complete and solve the working equation that represents the original price, p , of the shirt.
p + 7.98
p= $
p + 7.98 = 2 * 7.98
To solve for p, we can simplify the equation:
p + 7.98 = 15.96
Subtracting 7.98 from both sides:
p = 7.98
Therefore, the original price of the shirt was $15.96.
The working equation that represents the amount, a, Mike paid for buying 8 yards of ribbon is:
a/8 = $3.50
To solve for a, we can multiply both sides of the equation by 8 to get:
a = 8 * $3.50
a = $28.00
Therefore, Mike paid $28.00 for buying 8 yards of ribbon.
To solve the problem, we need to multiply the cost per yard by the number of yards purchased.
Given:
Number of yards purchased = 8
Cost per yard = $3.50
The equation representing the amount paid for 8 yards of ribbon can be written as:
a = (number of yards) * (cost per yard)
a = 8 * $3.50
Now, let's solve for a:
a = 8 * $3.50
a = $28.00
Therefore, Mike paid $28.00 for buying 8 yards of ribbon.
