D)
10.75abc

Answer 1

Answer:

Option B. $4.5a+4b+2.25c$

Step-by-step explanation:

we know that

The expression equivalent to a single day of ice cream sales is equal to

(Observing the table)

$a(1.75)+b(2.25)+a(2.75)+c(2.25)+b(1.75)$

Group terms that contain the same variable

$(a(1.75)+a(2.75))+(b(2.25)+b(1.75))+c(2.25)$

Combine like terms

$(a(1.75+2.75))+(b(2.25+1.75))+c(2.25)$

$a(4.5)+b(4)+c(2.25)$

Rewrite

$4.5a+4b+2.25c$

Answer 2

Answer:

Option B: 4.5a + 4b + 2.25c

Step-by-step explanation:

Because if you work it out and write down everything then one of the things you write down should be 1.75a + 2.25b + 2.75a + 2.25c + 1.75b = 4.5a + 4b + 2.25c. The underlined portion is when you combine like terms.
