Answer:
tall candles = 39
Short candles = 52
Step-by-step explanation:
let tall candles be x
and short candles be y
No. Of candles sold = x + y =91
Money made from candles will be equal to = 8x + 5y = $572
These both are simultaneous linear equations.
x + y =91 ( multiply by 5)
5x + 5y = 455
8x + 5y = $572
Subtract them:
-3x = -117
x = -117/3
x = 39
put value of x in
x + y = 91
39 + y = 91
y = 91 - 39
y = 52
x shows tall candles so they are 39
y shows short candles so they are 52
Answer:
32 pennies to each friend and 314 pennies remaining
Step-by-step explanation:
For the first step, we need to divide 128 by 4 to get the amount of pennies she gave to each friend: 128/4 = 32
For the second step, we need to subtract 128 from 442 to find out how many pennies she has left: 442-128 = 314
Hope this helps!
