QuestionA 15-day vitamin supply costs \$1.62. Find the daily cost in cents, rounded to the nearest tenth.

Studdy Solution

STEP 1

Assumptions1. The cost of a15-day supply of vitamins is $1.62. We need to find the cost per day in cents3. We need to round to the nearest tenth of a cent, which is the same as rounding to the nearest thousandth of a dollar

STEP 2

First, we need to convert the cost of the vitamins from dollars to cents. We can do this by multiplying the cost in dollars by100.
$Cost\, in\, cents = Cost\, in\, dollars \\times100$

STEP 3

Now, plug in the given value for the cost in dollars to calculate the cost in cents.
$Cost\, in\, cents = \$1.62 \\times100$

STEP 4

Calculate the cost in cents.
$Cost\, in\, cents = \$1.62 \\times100 =162\, cents$

STEP 5

Now that we have the cost in cents, we can find the cost per day by dividing the total cost by the number of days (15).
$Cost\, per\, day = Total\, cost / Number\, of\, days$

STEP 6

Plug in the values for the total cost and the number of days to calculate the cost per day.
$Cost\, per\, day =162\, cents /15\, days$

STEP 7

Calculate the cost per day.
$Cost\, per\, day =162\, cents /15\, days =10.\, cents$

STEP 8

Since we need to round to the nearest tenth of a cent, we round10.8 cents to10.8 cents as it is already at the nearest tenth of a cent.
The vitamins cost10.8 cents per day.
