Pls can someone me. i m giving 10 pts . i may mark you as the braniliest

the ratio of the number of $2 notes to the number of $5 notes was 4: 1. the total value of the notes was $260. how many notes were there altogether?
no need to give the calculation . just answer

100 notes were altogether

Solution:

Given that ratio of the number of $2 notes to the number of $5 notes was 4 : 1

number of $2 notes : number of $5 notes = 4 : 1

Let 4x be the number of $ 2 notes

Let 1x be the number of $ 5 notes

Given that total value of notes is $ 260

Therefore,

$ 2 (number of $ 2 notes ) + $ 5(number of $ 5 notes ) = $ 260

$ 2(4x) + $ 5(1x) = $ 260

8x + 5x = 260

13x = 260

x = 20

Thus number of notes altogether is given as:

4x + 1x = 4(20) + 1(20) = 80 + 20 = 100

Thus 100 notes were altogether

b) 36

step-by-step explanation:

18 times 2 is 36

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450
