a. Solution:

b. Explanation:

Answer 1

The numerical expression to find the cost of the apples and bananas is (4 x 0.50) + (1 x 0.80) and the cost is $2.80.

Sylvia bought 4 bananas and it cost her 50 cents each. She also bought an apple which cost her 80 cents.

The total cost in dollars is:  

= Cost of bananas + Cost of apples

= (Number of bananas x Cost of each banana) + (Cost of apple x Cost of each apple)

= (4 x 0.50) + (1 x 0.80)

The cost would be:

=  (4 x 0.50) + (1 x 0.80)

= $2.80

In conclusion, the cost of the apples and bananas would be $2.80.

Answer 2

Answer:

(4x0.50) + (1x0.80)=$2.80

Step-by-step explanation:

Multiply 4 with 0.50(because 5o cents is 0.50) to get 2. Then add 0.80 cents to 2. So you get $2.80
