Evaluate 5(x) - 2(y) + 2 for x= 5 and y=4
A) 15
B) 20
C) 25
D) 10

19

Step-by-step explanation:

if x=5 and y = 4 then

5(x)-2(y)+2

= 5×(5) -2×(4) +2

= 25-8+2

=19

y = 12x

Step-by-step explanation:

Given that:

y = cost of making a special order cupcake

A dozen of special order cupcakes = 12 pieces

Let the cost of extra ingredient for making a special order cupcake = x

Hence the cost y of making a dozen of such special order will be :

y = extra cost per order * number of orders

y = 12x
