## Task 1 - 060511

According to the annual plan, a cement plant is to produce 16400 t of cement in the second half of the year. In July, 2430 t were produced, in August 2310 t, in September 2680 t, in October 2830 t, and in November 2940 t.

a) Calculate the sufficiently smallest number of tons of cement that must be produced in December for the plant to meet its plan!

b) Calculate the price of this quantity from December if one ton of cement costs 39,- MDN!
a) From July to November, the production was (in tons): $2430+2310+2680+2830+2940=13190$ tons. Since the target is 16400 tons, $16400 \mathrm{t}-13190 \mathrm{t}=3210 \mathrm{t}$ must be produced in December.

b) With $39 \cdot 3210=125190$, the price for 3210 t of cement is 125190 MDN.
