Answer:
10.54 pounds is right answer
Step-by-step explanation:
bananas 2.26 pounds
Grapes 1.5 pounds
water melon 6.78 pounds
total weight = 10.54 pounds
Let, the cost of a belt = x
cost of a wallet = y
Then, system of equations would be:
x + y = 42
7x + 4y = 213
Multiply 1st equation by 4,
4x + 4y = 168
Substitute it from 2nd equation,
3x = 45
x = 15
Now, substitute it in 1st equation,
15 + y = 42
y = 42 - 15 = 27
In short, Belt costs $15 and wallet costs $27
Hope this helps!
