Part a) [tex]\$5x+\$2,25[/tex]
Part b) [tex]\$8x+\$18[/tex]
Part c) [tex]\$5x+\$3[/tex]
Step-by-step explanation:
The complete question in the attached figure
Part a) Two large cheese pizzas and three large pepperoni pizzas are
ordered. Write and simplify an expression that represents the
total cost total cost
we know that
The total cost is equal to the cost of two large cheese pizzas plus the cost of three large pepperoni pizzas
step 1
The cost of two large cheese pizzas is
[tex]2x[/tex]
step 2
The cost of three large pepperoni pizzas is
[tex]3(x+0.75)[/tex] ----> looking at the table for one topping
therefore
The total cost is
[tex]2x+3(x+0.75)[/tex]
[tex]2x+3x+2,25[/tex]
[tex]\$5x+\$2,25[/tex]
Part b) Write and simplify an expression that represents the total cost of
eight large pizzas, if two are cheese and six have four toppings
each.
we know that
The total cost is equal to the cost of two large cheese pizzas plus the cost of six large pizzas with four toppings
step 1
The cost of two large cheese pizzas is
[tex]2x[/tex]
step 2
The cost of six large pizzas with four toppings is
[tex]6(x+3)[/tex] ----> looking at the table for four toppings
therefore
The total cost is
[tex]2x+6(x+3)[/tex]
[tex]2x+6x+18[/tex]
[tex]\$8x+\$18[/tex]
Part c) Elsa orders three large cheese pizzas, a large pepperoni and
mushroom pizza, and a large green pepper and onion pizza.
Write and simplify an expression that represents the total cost
we know that
The total cost is equal to the cost of three large cheese pizzas plus the cost of two large pizzas with two toppings each
step 1
The cost of three large cheese pizzas is
[tex]3x[/tex]
step 2
The cost of two large pizzas with two toppings each is
[tex]2(x+1.50)[/tex] ----> looking at the table for two toppings
therefore
The total cost is
[tex]3x+2(x+1.50)[/tex]
[tex]3x+2x+3[/tex]
[tex]\$5x+\$3[/tex]
