Mathematical Equivalence

ON

Answer explanation

1) Add the fractions = how many cans are eaten per day.

2) Convert the fraction to a decimal.

3) multiply that number by 60 (# of days supply)

4) That gives you the number of cans you need.

5) multiply that by the cost of each can.

6) divide by 2 because its BOGO free,

Two gyms offer different membership plans. The tables show the total costs of the plans at Gym A and Gym B for different numbers of months.

What amount represents the constant of proportionality for the plan that shows a proportional relationship?

Mathematical Equivalence

ON

Answer explanation

In the proportional table, the membership costs $30 per month regardless of how many months. Since the constant of proportionality can be a unit rate, 30 is the constant of proportionality for this one.

A clothing store is having a sale. All items are on sale for 35% off the original price. Create an equation in terms of p, the original price of an item, to show the sale price of the item before any sales tax.

Choose the equation that best represents the situation.

• .35p + .65p = p

• p - .35p = .65p

• p - .65p = .35p

• .65p - .35p = p

Answer explanation

1) The original price is p

2) p is 35% off, which means we need to TAKE AWAY 35% from p.

3) Convert 35% into a decimal

4) 35% = .35

5) p - .35p = ?

6) 1 - .35 = .65

7) p - .35p = .65p
