The cost of 10 apples = $6.5
Explanation:
To determine the cost for 10 apples, we need to find the cost for 1 apple
let x be the cost of one apple
7 apples = $4.55
1 apple = x
cross multiply:
7x = 4.55(1)
7x = 4.55
x = 4.55/7
x = 0.65
The cost of one apple = $0.65
The cost of 10 apples = 10 × $0.65
The cost of 10 apples = $6.5
