Answer:

49

Step-by-step explanation:

To find the number of color pencils sold you simply multiply the number of color pencils by the number of 1st classes:

#color\ pencils\ sold=(color\ pencils\ sold\ per\ class)(number\ of \ 1st\ G\ classes)

- each class sold 7 color pencils

- there are seven 1st G classes

Then, you replace in the formula and you obtain:

color\ pencils\ sold=(7)(7)=49

hence, there were 49 color pencils sold

Daniel has $25 to spend at the fair. If the admission to the fair is $4 and the rides cost $1.50 each , what is thw greatest num
kondor19780726 [428]
$25 is the total amount of money.
Admission is a constant, meaning that price will not vary and is fixed.
The rides each cost something so the price of rides will vary, unlike the constant (admission). 

Thus making x the number of rides, we have the equation:
25 = 4 + 1.5x.
We need to solve for x, but x must be a whole number so we will round down if the solution is not an integer.

1.5x = 21
Divide by 1.5 on both sides.
x=14

Daniel can go on 14 rides maximum.
