Q. David is making rice for his guests based on a recipe that requires rice, water, and a special blend of spice, where the rice-to-spice ratio is 15:1. He currently has 40 grams of the spice blend, and he can go buy more if necessary. He wants to make 10 servings, where each serving has 75 grams of rice. Overall, David spends 4.50 dollars on rice.How many servings can David make with the current amount of spice he has?□ servings
Calculate Rice Amount: First, we need to determine the total amount of rice David needs for 10 servings, where each serving is 75 grams of rice.Calculation: 10 servings ×75 grams per serving =750 grams of rice needed.
Calculate Spice Amount: Next, we need to calculate how much spice is required for the 750 grams of rice, using the rice-to-spice ratio of 15:1. Calculation: For every 15 grams of rice, 1 gram of spice is needed. Therefore, for 750 grams of rice, we need 15750grams=50 grams of spice.
Check Spice Quantity: Now, we compare the amount of spice David has (40 grams) with the amount of spice required (50 grams) to determine if he has enough spice for 10 servings.Calculation: David has 40 grams of spice, but he needs 50 grams for 10 servings.
Determine Servings with Available Spice: Since David does not have enough spice for 10 servings, we need to find out how many servings he can make with the 40 grams of spice he currently has.Calculation: If 1 gram of spice is needed for 15 grams of rice, then 40 grams of spice is enough for 40×15=600 grams of rice.
Calculate Available Servings: Finally, we calculate how many servings of 75 grams of rice can be made from 600 grams of rice.Calculation: 75grams per serving600grams of rice=8servings.
