Question

Adam owns an inline skate shop. Adam wants to buy eight thousand four hundred fifty-eight inline skate wheels. Inline skate wheels sell in sets of four. A set of four skate wheels cost six dollars and forty-seven cents. How much money does Adam spend to buy eight thousand four hundred fifty-eight wheels? Adam puts eight wheels on every pair of inline skates. On how many pairs of inline skates can Adam put eight wheels? Between what two whole numbers is the number of pairs of inline skates Adam can put wheels on? Show all your mathematical thinking

Answer 1

Cost: $13,680.82

Number of pairs of skates: 1057.25 / 1057-1058

Explanation:

To find the cost of the wheels, we need to multiply the cost of a set, $6.47, by the number of wheels needed, 8458, for a quotient of 54723.26. We then divide this quotient by 4, the number of wheels in each set, to get the cost of $13,680.82.

Next, to find the number of pairs that Adam can put wheels on, we divide 8458, the number of wheels Adam has, by 8, the number of wheels Adam puts on each pair of skates. This leaves us with a quotient of 1057.25 pairs. The two whole numbers this number is between are 1057 and 1058.
