Answer:

32 Nickels

Step-by-step explanation:

Given

Coins: Nickels (N) and Dimes (D)

$0.05 = 1 nickel and $0.10 = 1 dime

So, the amount implies:

0.05N + 0.10D = 6.20

The number of coin implies:

D = 14 + N

Required

Determine the number of nickels found

Substitute 14 + N for D in 0.05N + 0.10D = 6.20

0.05N + 0.10(14 + N) = 6.20

0.05N + 1.4 + 0.10N = 6.20

Collect Like Terms

0.05N + 0.10N = 6.20 - 1.4

0.15N = 4.8

Solve for N

N = 4.8/0.15

N = 32

Hence, he found 32 nickels

Jaxson buys ice cream and apples at the store. He pays a total of $24.81. He pays a total of $3.60 for the ice cream. He buys 7
Vadim26 [7]

Answer:

$3.03

Step-by-step explanation:

7x + $3.60 = $24.81

Subtract $3.60 from both sides of the equation:

7x + $3.60 - $3.60 = $24.81 - $3.60

7x = $24.81 - $3.60

7x = $21.21

Divide each side by 7:

(7x/7) = ($21.21/7)

x = ($21.21/7)

x = $3.03
