Answer:

The answer to your question is He bought 7 large candles and 9 small candles.

Step-by-step explanation:

Data

Large candles = L cost = $7

small candles = s cost = $3

Total cost = $76

Total candles = 16

Process

- Write two equations

L + s = 16 ------------ (I)

7L + 3s = 76 ------------- (II)

- Solve the system of equations by elimination

Multiply equation I by -7

-7L - 7s = -112

7L + 3s = 76

Simplify

0 - 4s = - 36

Solve for s

s = -36 / -4

s = 9

Substitute s in equation I

L + 9 = 16

Solve for L

L = 16 - 9

L = 7
