If 24 students went on a field trip, and 24 students represented eight tenths of the class, then
.
First, multiply by 10 on both sides.
240 = 8x
Divide by 8 on both sides.
x = 30.
The class has 30 students in all.
This is, however, only the equation way to solve.
Answer:
2000
Step-by-step explanation:
2(20x30)+ 2(8x30) + 2(20x8).
Given:
Price paid including tax: $37.48
sales tax = 5%
This means that $37.48 is equivalent to 105%
To get the value of the 100% or its original price, we divide the price paid by its percentage rate
$37.48 ÷ 1.05 = $35.70 value of the original price
$35.70 * 5% = $1.78 value of sales tax
$35.70 + 1.78 = $37.48
We need to know the "unit of measure" ( ie metre, gram etc) and
the number of units.
ie 10 (No of Units) Metre (Unit of measure)
