POSSIBLE POINTS: 0.5 A plumber charges S65 per hour plus a $100 inspection fee. The cost for x hours of work is given by the function S(x) = 65x + 100. If the plumber
charges by the whole hour, what are the reasonable domain and range for the function? Use set notation when writing your answer

but there’s no any figure there!

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74

answer: not good

step-by-step explanation:

try this. the error is that sariah was combining a constant (4.5) with a variable with a coefficient, thus getting an inaccurate answer.

this is also assuming that you meant to put an equal sign before the 4.5 + x 35 x

to solve this problem, the strategy used is just to solve it yourself and find the correct answer by combining like terms.

hope this !
