Rx: keflex 125 mg, take 10 ml by mouth 4 times a day for 10 days how many mg will the patient have taken at the end of 10 days? if there are only 120 ml vials available, how many vials will be used to fill this prescription

400ml will be taken at the end of 10days

280ml will be used to fill this prescription

Step-by-step explanation:

10ml four times a day = 40ml per day

Therefore 10days = 40 x 10 = 400ml

If there is only 120ml available.

400ml - 120ml = 280ml

280ml will be used to fill this prescription

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
