Question

At the market, Joey buys 3 avocados for $0.40 Each and 5 lemons for $0.40 each. The cashier in training rings up 3x0.40 and then 5x0.40 to get the total. The experienced cashier says to add the 3 plus 5 in his head and then ring up 8x0.40. What property says that these two totals would be the same

Answer 1

Answer:

Distributive property

Step-by-step explanation:

Distributive property states that,

multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

That is,

a(b + c) = ab + ac

3 avocados cost $0.40 each

3x0.40

= $1.2

5 lemons cost $0.40 each.

5x0.40

= $2

Total = $1.2 + $2

= $3.2

Using distributive property

(3+5)0.40

= 8(0.40)

= $3.2
